For power efficiency, High Power Amplifiers (HPAs) used in satellite communications must be operated as close as possible to saturation. This constraint especially results in nonlinear amplitude distortions of the transmit signals. In this paper, the impact of these distortions on the performance of a linearly precoded 2 x NR Multiple-Input-Multiple-Output (MIMO) Single Carrier Geostationary Earth Orbit (GEO) satellite system operated for fixed satellite services (FSS) and using PSK modulation is analyzed. In order to combine channel coding and modulation, a Bit-Interleaved-Coded-Modulation with Iterative Decoding (BICM-ID) scheme is considered. Through EXIT charts and BER simulations, it is shown that a phase precoder which aims at maximizing the input-output mutual information and doesnt increase the Peak-to-Average-Power-Ratio (PAPR) of the transmit signals, is a robust strategy in this context when QPSK symbols are used for bit-to-symbol mapping.

Multi-beam mobile satellite systems aim at providing broadband and high speed mobile services over a large area to achieve a high system throughput, where hybrid space-ground beamforming is one of the most promising candidates for ground-based beamforming techniques. It not only reduces the feeder link bandwidth to save spectral resources, but also takes advantages of both the on-ground and on-board processing, exhibiting a good trade-off of the performance and the space/ground complexity. In this paper, we propose an efficient hybrid space-ground precoding technique for multi-beam mobile satellite systems. It consists of coarse on-board beamforming and reduced-rank on-ground beamforming based on the feed selection of the phased array antenna. The advantages of the proposed hybrid precoding are shown as compared to the fully on-ground beamforming as well as the existing solutions.

Tomlinson-Harashima precoding (THP) is a popular nonlinear interference mitigation technique employed at the transmitter side which can provide better performance in comparison with linear precoding technique with a slight increase in complexity. It can be considered as a dual to the successive interference cancellation (SIC). In this paper, we focus on a new THP scheme for the downlink of multiuser multiple-input multiple-output (MIMO) systems with decentralized receivers. In contrast to previous approaches, the proposed algorithm allows the provision of transmitting different types of information simultaneously subjected to different Quality of Service (QoS) requirements of each active user. This algorithm is based on minimum mean square error (MMSE) criterion and the closed-form solution of the processing matrices is found by applying Cholesky factorization with symmetric permutation. For this THP algorithm, by suitably ordering the rows of channel matrix we can obtain better performance. Moreover, it significantly improves the bit error rate (BER) performance as well as the achievable rate as compared with zero-forcing (ZF) THP available in the literature, which can be shown from simulation results.

Modern mobile terminals produce massive small data packets. For these short-length packets, it is inefficient to follow the current multiple access schemes to allocate transmission resources due to heavy signaling overhead. We propose a many-access scheme that is well suited for the future communication systems equipped with many receive antennas. The system is modeled as having a block-sparsity pattern with unknown sparsity level (i.e., unknown number of transmitted messages). Block precoding is employed at each single-antenna transmitter to enable the simultaneous transmissions of many users. The number of simultaneously served active users is allowed to be even more than the number of receive antennas. Sparsity-aware recovery is designed at the receiver for joint user detection and symbol demodulation. To better recover the transmitted block-sparse signal vector, interference cancellation based block orthogonal matching pursuit (ICBOMP) algorithm is developed upon the known BOMP algorithm for the recovery. Simulation results demonstrate the effectiveness of the proposed scheme in small packet services, as well as the advantages of ICBOMP in improving signal recovery accuracy and reducing computational cost.

This paper focuses on the pilot contamination precoding (PCP) assisted sum rate maximization for multicell massive MIMO system with finite number of antennas at base station (BS). Considering the case where BSs with finite number of antennas, the impact of the noise, the channel estimation error, channel uncertainty caused by usage of statistical channel state information (CSI) and channel non-orthogonality on the system performance can not be neglected any more compared with the pilot contamination, we in this work jointly consider all these factors and formulate an optimization problem to maximize the sum rate of all users. We derive the expression of the PCP matrix maximizing sum rate (MSR) of all users. Based on the obtained expression, an iterative algorithm is proposed to get a suboptimal solution to maximize the sum rate of all users. Simulations have been done to verify its superiority and results show that the proposed MSR-PCP outperforms the existing zero forcing PCP (ZF-PCP) and max-min PCP with acceptable computational complexity, especially for the case where users are located at cell edges and suffer from strong interference.

In this paper, we investigate energy-efficient hybrid precoding which consists of baseband precoding and radio frequency (RF) precoding for Millimeter Wave (mmWave) systems over multi-input multi-output (MIMO) interference channels. The considered optimization problem is intractable because both the object function and the constraint are non-convex. Instead of solving the multivariate optimization problem directly, we propose a near-optimal algorithm which includes two steps. First, the original problem is reformulated into an equivalent univariate optimization problem. Second, a near-optimal hybrid precoder is obtained via an orthogonal matching pursuit (OMP) based algorithm. Numerical results verify that the proposed hybrid precoding algorithm achieves a near-optimal EE performance. Moreover, the energy efficiency (EE) maximization algorithm outperforms the sum rate maximization algorithm in terms of the EE performance, especially at high transmit power.

Heterogeneous network (HetNet) is a promising technology to improve the capacity of future generations of cellular network, in which a mobile station can be served by multiple base stations (BSs) with different scales of coverage range, including short range low power nodes (LPNs). In HetNet, a major challenge is how to provide guaranteed quality-of-service (QoS) for all users. To address this issue, we investigate a practical scenario in which the massive multiple-input multiple-output (MIMO) technology is adopted by the cooperation of one macro-cell BS and several LPNs. Furthermore, we provide a lightweight channel state information (CSI) acquisition scheme for the implementation. Numerical simulation results demonstrate that the signal-to-interference-and noise ratio (SINR) of intended users in LPNs covered with small cells can be significantly increased by this proposed massive MIMO precoding scheme, whereas oppressing the impact on neighboring victim users.

This paper analyzes the impact of uncertain channel information for a Tomlinson-Harashima precoder designed with the zero forcing criterion. The channel uncertainty is modeled as the channel matrix corrupted by additive Gaussian noise. General expressions are derived for the densities of the feedback and feedforward precoding matrices. Under an assumption of small variance in the channel uncertainty, asymptotic expressions are derived for both the two-user case and the general multiple users case.

In this paper, we investigate the impact of massive MIMO and distributed preceding on the performance of densified cellular networks via large system analysis. Based on the fact that the network rate performance of the cellular networks is scale invariant with reduced cell size, we want to find out if the interference of large scale dense cellular networks can be alleviated by the use of large scale antennas. We first derive the deterministic approximation of the users' SINR based on random matrix theory and show that the sum rate grows logarithmically with the number of transmit antennas in the base stations and the sum rate saturates quickly when the SNR increases even with very large number of antennas. To overcome the performance ceiling, a large system analysis of precoding with local channel state information under the framework of virtual signal to interference plus noise ratio (VSINR) is presented. The asymptotic results show that the VSINR precoding is also interference limited in high SNR. While as a special case, the limiting VSINR precoding can make the sum rate grow linearly with SNR in dB. We conclude that by combining large scale antennas and distributed precoding, we can efficiently tap the potential of large scale dense cellular networks without much network coordination.

In this paper, a novel differential precoding scheme which employs a differential codebook to update the precoding matrices, is proposed for LTE systems. Due to the temporal correlation of the adjacent channel matrices, the consecutive precoding matrices are likely to be similar. This approach quantizes only the differential information of the channel instead of the whole channel subspace, which virtually increases the codebook size to realize more accurate quantization of the channel. Moreover, the proposed precoding utilizes only 8-PSK constellations for codebook design so that it is perfectly compatible with LTE codebooks. The capacity of the proposed codebook performs almost 1.5 dB better than those of any other non-differential codebooks with the same amount of feedback information.
