Relay-Selection Improves the Security-Reliability Trade-off in Cognitive Radio Systems
Yulong Zou, Benoit Champagne, Wei-Ping Zhu +1
We consider a cognitive radio (CR) network consisting of a secondary transmitter (ST), a secondary destination (SD) and multiple secondary relays (SRs) in the presence of an eavesd…
Spectral and Energy Spectral Efficiency Optimization of Joint Transmit and Receive Beamforming Based Multi-Relay MIMO-OFDMA Cellular Networks
Kent Tsz Kan Cheung, Shaoshi Yang, Lajos Hanzo
We first conceive a novel transmission protocol for a multi-relay multiple-input--multiple-output orthogonal frequency-division multiple-access (MIMO-OFDMA) cellular network based…
Maximizing Energy-Efficiency in Multi-Relay OFDMA Cellular Networks
Kent Tsz Kan Cheung, Shaoshi Yang, Lajos Hanzo
This contribution presents a method of obtaining the optimal power and subcarrier allocations that maximize the energy-efficiency (EE) of a multi-user, multi-relay, orthogonal freq…
