“…As reported in [5], [11], [20], and [21], the performance of SISO-MSDSD is dominated by the detection window-size. A significant performance gain can be obtained by increasing its window-size, but at the cost of computational complexity.…”

Polar codes (PCs) have attracted significant attention in the last decade, especially after their adoption in the forthcoming 5G wireless networks. However, previous studies focused on coherent polar codes, which always rely on the strong assumption of available perfect channel state information. Instead, in this paper, we investigate the use of PCs in noncoherent systems. First, a binary differential phase shift keying (BDPSK) demodulator is concatenated with a polar decoder to form the noncoherent detector, where successive cancellation (SC) is applied. The simulation results demonstrate that the SC-based PCs for noncoherent detection have approximately a discrepancy of only 3 dB compared with the coherent counterpart in noncoherent channels. Furthermore, in order to further decrease this discrepancy, we replace the BDPSK demodulator with a soft-input soft-output (SISO) multiple symbol differential sphere decoding demodulator. Similarly, the SC-based PC decoder is replaced by the SISO belief propagationbased PC decoder, and by using this novel architecture, an iterative noncoherent detector is constructed. Benefiting from further invoking extrinsic information transfer chart tool and the dynamic window-size detection scheme, the performance of the proposed iterative noncoherent detector becomes competitive with its coherent one in practical applications, since the performance degradation is reduced to 1 dB.

“…However, generally for a system with a good backhaul link, DF outperforms the others, while for a system with a poor backhaul link, AF or CF are more advantageous [2]. There are three types of relay: fixed, nomadic (special events indoors), and mobile relays (in trains, as we will see in the forthcoming chapters) [69]. An example of relaying scenario is shown in Fig.…”

Development in Iraq for their financial support. Without this support, it would have been impossible to undertake my Ph.D. program at the University of Kent.Last but not least, I would like to thank my father and mother for their continuous motivation and for always believing in me, and also for their endless love and support. Also, I am profoundly indebted to my beloved wife for her continuous love, support, and understanding of my Ph.D. pressure and lack of time. In addition to all the time she has given to taking care of our small family during those four years. Without her this thesis would not have been possible.

“…A critical issue in FD communications is that the selfinterfering signal from the FD transmitter is much stronger than the intended receiving signal. Thanks to advanced self-interference cancellation techniques developed in recent years, both in analog and digital signal processing, FD communications have been introduced in recent fifth-generation (5G) standard proposals as an appealing technique to significantly enhance the attainable spectral efficiency of communication systems [1][2][3].…”

This paper is concerned with wireless relay networks that employ K full-duplex (FD) decode-and-forward relays to help a source to communicate with a destination. Each FD relay is equipped with multiple antennas, some for receiving and some for transmitting. The paper considers joint relay-antenna selection schemes that are based on the instantaneous channel conditions for two cases of antenna configurations, namely fixed antenna configuration (FAC) and adaptive antenna configuration (AAC). Under FAC, the transmit and receive antennas at each relay are fixed, whereas in the case of AAC an antenna at a relay can be configured to be either a transmit or a receive antenna. In addition to equal power allocation between the source and selected relay, a power scaling approach to counteract the effect of residual self-interference is also examined. Closed-form expressions of the outage probability and average capacity are obtained and provide important insights on the system performance. The accuracy of the obtained expressions are corroborated by simulation results. In particular, it is shown that under FAC and without power scaling, the diversity order approaches K as the self-interference (SI) level gets smaller, while it approaches zero whenever the SI level is nonzero and the SNR increases without bound. Under FAC and with power scaling, the diversity order approaches K for any SI level. For the case of AAC and without power scaling, the diversity order approaches 2K for small SI level. When power scaling is applied in AAC, the diversity order approaches 2K at any SI level.
