This paper investigates the achievable sum-rate of massive multiple-input multiple-output (MIMO) systems in the presence of channel aging. For the uplink, by assuming that the base station (BS) deploys maximum ratio combining (MRC) or zero-forcing (ZF) receivers, we present tight closed-form lower bounds on the achievable sum-rate for both receivers with aged channel state information (CSI). In addition, the benefit of implementing channel prediction methods on the sum-rate is examined, and closed-form sum-rate lower bounds are derived. Moreover, the impact of channel aging and channel prediction on the power scaling law is characterized. Extension to the downlink scenario and multicell scenario is also considered. It is found that, for a system with/without channel prediction, the transmit power of each user can be scaled down at most by 1/√M (where M is the number of BS antennas), which indicates that aged CSI does not degrade the power scaling law, and channel prediction does not enhance the power scaling law;instead, these phenomena affect the achievable sum-rate by degrading or enhancing the effective signal to interference and noise ratio, respectively. © 2015 IEEE.

This paper investigates the achievable throughput of a multi-antenna two-hop relay link under hybrid full/half-duplex operation. The analysis is facilitated by realistic waveform simulations, which explicitly model all the essential circuit impairments occurring in the relay transceiver together with degrading channel estimation and self-interference cancellation. The obtained results indicate that pure full-duplex operation does not ensure optimal performance but additional half-duplex transmission periods are usually needed to maximize the end-to-end throughput. Especially, it is shown that the estimation of the self-interference channel within the relay should be performed when the source is not transmitting anything while also the source should be allowed to transmit alone to avoid making the first hop a bottleneck. These findings form a solid basis for optimizing the full-duplex MIMO relay deployments in future mobile networks.

Detector-device-independent quantum key distribution (DDI-QKD) held the promise of being robust to detector side channels, a major security loophole in quantum key distribution (QKD) implementations. In contrast to what has been claimed, however, we demonstrate that the security of DDI-QKD is not based on postselected entanglement, and we introduce various eavesdropping strategies that show that DDI-QKD is in fact insecure against detector side-channel attacks as well as against other attacks that exploit devices’ imperfections of the receiver. Our attacks are valid even when the QKD apparatuses are built by the legitimate users of the system themselves, and thus, free of malicious modifications, which is a key assumption in DDI-QKD.

A rigorous performance analysis of Fano coding is presented, providing an upper bound on the average codeword length of binary and ternary Fano codes for an arbitrary discrete memoryless source. The performance bound is slightly better than Shannon's well-known bound for Shannon coding. As a by-product a novel general lower bound on Shannon entropy is derived that might be of interest also in a different context. This bound is expressed with the help of variational distance and provides a special case of a reverse Pinsker inequality.

In the recent past the concept of MIMO (multiple input multiple output) transmission over multimode fibers has attracted increasing interest in the optical fiber transmission community, targeting at increased fiber throughput or improved bit-error rate performance. In this contribution a coherent (2 ×2) MIMO (multiple input multiple output) transmission with iterative detection over a measured multimode fiber channel at 1325 nm as well as at 1570 nm operating wavelength is studied under the constraint of a given fixed data throughput and integrity. For the channel measurements a fibre length of 1,4 km were chosen. Extrinsic information transfer (EXIT) charts are used for analyzing and optimizing the convergence behaviour of the iterative demapping and decoding. Our results show that in order to achieve the best bit-error rate, not necessarily all MIMO layers have to be activated. © Springer-Verlag Berlin Heidelberg 2014.

In the recent past the concept of MIMO (multiple input multiple output) transmission over multimode fibers has attracted increasing interest in the optical fiber transmission community, targeting at increased fiber throughput or improved bit-error rate performance. Mostly, the possible performance improvements are calculated by computer simulations, which require some knowledge about the underlying system. Here, measurements results can be helpful to improve the quality of the estimated performance improvements. That’s why in this contribution a signal theoretic multiple-input multiple-output (MIMO) system model for estimating modal and chromatic dispersion is developed. Based on channel measurements within a 1,4km MIMO multimode channel parameters for modal and chromatic dispersion are estimated. Furthermore, taking given parameters of the dispersion into account, the introduced signal theoretic MIMO system model enables a reconstruction of the MIMO specific impulse responses. © Springer-Verlag Berlin Heidelberg 2014.
