In the *** frequency range (up to 212 MHz), the diagonal dominance structure of the channel matrix is no longer valid at the higher frequencies. As a result, the linear Zero Forcing (ZF) precoder in combination with dynamic spectrum management (DSM) is no longer near-optimal for downstream vectored *** transmission. To boost performance, we develop a novel low-complexity algorithm for both linear and non-linear precoding based DSM that maximizes the weighted line sum-rate under realistic per-line total power and per-tone spectral mask constraints. The algorithm relies on a Lagrange multiplier based transformation of the downstream dual decomposition approach formulation into its dual upstream formulation, together with a low-complexity iterative fixed-point formula to solve the resulting upstream problems. Simulations with measured *** channel data up to both 106 and 212 MHz are provided revealing a significantly increased performance of this algorithm over linear ZF precoding.

This paper considers interference mitigation techniques in the forward link of multibeam satellite systems. In contrast to previous works, either devoted to receiver interference mitigation (e.g. multiuser detection) or transmitter interference mitigation (precoding), this work evaluates the achievable rates of the joint combination of both techniques. On the one hand, precoding cannot properly mitigate all the inter-beam interference while maintaining a sufficiently high signal-to-noise ratio. On the other hand, the receiver cost and complexity exponentially increases with the number of signals to be simultaneously detected. This highlights that the receiver cannot deal with all the interferences so that in general only 2 signals are jointly detected. As a result, the use of precoding within a coverage area jointly with multiuser detection can both benefit from each other and extremely increase the achievable rates of the system. This is numerically evaluated in a close-to-real coverage area considering simultaneous non-unique decoding strategies. The results show the benefits of this joint scheme that eventually can increase the current precoding performance a 23%.

In this study, a quantization feedback algorithm based on error comparison is proposed aiming at the characteristics of base station cooperation system. The algorithm quantizes the channel vector by several steps. During the quantization, the error is compared before the quantization in each step, which reduces the accumulation of quantization error. Meanwhile, the complexity of computation is decreased greatly. It has been shown in complexity analysis and system simulation that compared with the existing global feedback schemes and individual feedback schemes, the proposed scheme achieves a good balance between complexity and system performance.

This paper focuses on the transceiver design for multiple-input-multiple-output (MIMO) interference channel. The optimization objective is to minimize the maximum perstream mean square error (MSE) which greatly influences the bit error rate (BER) performance. Considering the imperfect channel state information (CSI) in reality, we propose two robust algorithms based on statistical and bounded CSI error models, respectively. For statistical CSI error model, the maximum average per-stream MSE is minimized while the worst-case perstream MSE is optimized for bounded CSI error model. We utilize an alternate optimization approach to iteratively update the precoding and receiving matrices since the robust min-max per-stream MSE problems are not jointly convex. The objective is monotonically decreased and lower bounded, so the convergence of the algorithms is guaranteed. The improved performance and robustness of the proposed algorithms are verified by simulations.

In this paper we study the hybrid precoding design problem for a frequency selective massive MIMO channel, e.g., the millimeter wave (mmWave) massive MIMO channel. In contrast to a traditional MIMO system, a hybrid analog-digital MIMO scheme is preferred for massive MIMO systems due to the high cost and power consumption of the radio frequency (RF) chains. The RF analog precoding is implemented using only phase shift networks, which impose constant modulus constraints on the RF precoding and decoding matrices. Moreover, there is just one common equivalent RF beamforming matrix for all subcarriers. The resulting sum rate maximization problem is non-convex and, therefore we resort to suboptimal solutions. Two methods are introduced, namely, the higher order SVD (HOSVD) based design and the sequential low rank unimodular approximation based design. The former approach exploits the truncated HOSVD of the equivalent channel while the latter approach approximates optimal unconstrained solutions by low rank unimodular approximations. Simulation results show that when the mmWave channel model is used, both approaches outperform the extension of the state of the art compressed sensing based algorithm to the multi-carrier case.

In this paper, we propose several precoding methods to reduce the interference caused by Faster-Than-Nyquist (FTN) signaling for Orthogonal Frequency Division Multiplexing Offset Quadrature Amplitude Modulation (OFDM/OQAM). The proposed precoders are combined with an FTN-OFDM/OQAM modulator to pre-cancel the interference at the transmitter side. An iterative receiver for each precoding scheme is also presented. With the simulations, we show that the convergence speed of the FTN-OFDM/OQAM transceiver increases with the proposed precoders.

Hybrid analog and digital precoding is one possibility for making the communication in the underutilized millimeter-wave frequency bands viable for future cellular networks. This paper proposes new algorithms for the design of hybrid precoders in the downlink of a multi-user scenario. The algorithms are based on the Linear Successive Allocation (LISA) method developed for the traditional fully digital precoding. It successively allocates data streams to users and suppresses the inter-stream interference in two steps. By a simple approximation, the two steps are mapped to the analog and digital domain to obtain the new multi-user hybrid precoding algorithm Hybrid LISA (H-LISA). Furthermore, a low-complexity version is developed by exploiting the typical structure of mmWave channels. We also present modifications of H-LISA for hybrid analog and digital processing at the users and for the case that the phase shifts of practical phase shifters implementing the analog part of the hybrid processing are quantized. The good performance of the proposed methods is demonstrated by simulation results. In addition, we discuss the impact of channel estimation errors on the achievable sum rate.

Millimeter wave (mmWave) experiences a high path-loss in free space. To overcome this weakness, antenna array is used to obtain a high beamforming gain. However, due to high complexity of digital beamforming systems, the hybrid structure consisting of baseband and analog precoder has been proposed. We consider the well known block diagonalization (BD) precoding for transmission technique. Because of the practical constraints such as channel estimation error, the limited number of radio frequency (RF) chains and the quantized analog phase shifters, the BD precoder cannot provide accurate interference-free effective channel. In this paper, we propose the extended BD precoding method which extends the null space of interference channels to reduce the effect of practical constraints. Simulation results show that the proposed method provides much improved sum rate and error performances than original BD precoder.

In this paper, we propose a new improved TH precoding algorithm, which intends to solve the problem of high bit error rate (BER) from traditional THP algorithm when the channel is in bad condition, and compare the performance with different classic ZF-THP and MMSE-THP. Also the conclusion is verified by emulation. Based on the Precoding module algebra, we proposed the Reduce Grid Algorithm which has high efficiency, and pre-coding scheme based on the Reduce grid algorithm, which can be used in non-ideal MIMO model.

This paper investigates artificial noise injection into the temporal and spatial dimensions of a legitimate wireless communication system to secure its transmissions from potential eavesdropping. We consider a multiple-input single-output (MISO) orthogonal frequency division multiplexing (OFDM) system in the presence of a single-antenna passive eavesdropper and derive both the secrecy rate and average secrecy rate of the legitimate system. It is assumed that the legitimate transmitter knows the full channel information of the legitimate transceivers but does not know the instantaneous channel state information of the passive eavesdropper. Closed-form expressions for the secrecy rate and average secrecy rate are derived for the asymptotic case with a large number of transmit antennas. We also investigate 1) the power allocation between the data and the AN;2) the power allocation between the spatial and the temporal AN. Computer simulations are carried out to evaluate the performance of our proposed artificial noise scheme.
