چکیده

In this paper, a multi-antenna assisted full-duplex (FD) relaying scheme with reliability-aware iterative decoding at the destination node is proposed to improve system spectral efficiency and reliability. This scheme allows the multi-antenna based FD relay node cancel the self-interference with QR-decomposition and forward its decoded signal to the destination node regardless the decoding errors. Then, by deploying our proposed reliabilityaware iterative detection/decoding process, the multi-antenna destination node mitigates inter-frame interference and error propagation effect. Simulation results show that, without extra cost of time delay and signalling overhead, our proposed scheme outperforms the conventional selective decode-and-forward (SDF) relaying schemes, such as cyclic redundancy check based S-DF relaying and threshold based S-DF relaying, by up to 8 dB in terms of bit-error-rate performances.

Performance and Energy Efficiency of Cognitive Full-Duplex under Spectrum Sharing Constraints

In a cognitive radio context under spectrum sharing constraints, a secondary network may transmit concurrently with the primary one as long as the communication of this latter is not compromised. For such an operation, a maximum allowable interference level at the primary receiver is defined, and secondary users (SUs) should take into account this threshold during the transmission in order to a...

Reliability-aware iterative detection scheme (RAID) for distributed IDM space-time codes in relay systems

In this article, distributed interleave-division multiplexing space-time codes (dIDM-STCs) are applied for multi-user two-hop decode-and-forward (DF) relay networks. In case of decoding errors at the relays which propagate to the destination, severe performance degradations can occur as the original detection scheme for common IDM-STCs does not take any reliability information about the first h...

Multi-Antenna Cooperative Wireless Systems: A Diversity-Multiplexing Tradeoff Perspective

We consider a general multiple antenna network with multiple sources, multiple destinations and multiple relays in terms of the diversity-multiplexing tradeoff (DMT). We examine several subcases of this most general problem taking into account the processing capability of the relays (half-duplex or full-duplex), and the network geometry (clustered or non-clustered). We first study the multiple ...

Full-Duplex Relaying with Half-Duplex Relays

We consider “virtual” full-duplex relaying by means of half-duplex relays. In this configuration, each relay stage in a multi-hop relaying network is formed by at least two relays, used alternatively in transmit and receive modes, such that while one relay transmits its signal to the next stage, the other relay receives a signal from the previous stage. With such a pipelined scheme, the source ...

Throughput and Expected-Rate in Wireless Block Fading Systems

This thesis deals with wireless channels in uncorrelated block fading environment with Rayleigh distribution. All nodes are assumed to be oblivious to their forward channel gains; however, they have perfect information about their backward channel gains. We also assume a stringent decoding delay constraint of one fading block that makes the definition of ergodic (Shannon) capacity meaningless. ...
