In this paper, we consider cooperative transmission in cognitive wireless relay networks (CWRNs) over frequency-selective fading channels. We propose a new distributed space-time-frequency block code (DSTFBC) for a two-hop nonregenerative CWRN, where a primary source node and multiple secondary source nodes convey information data to their desired primary destination node and multiple secondary destination nodes via multiple cognitive relay nodes with dynamic spectrum access. The proposed DSTFBC is designed to achieve spatial diversity gain as well as allow for low-complexity decoupling detection at the receiver. Pairwise error probability is then analysed to study the achievable diversity gain of the proposed DSTFBC for different channel models including Rician fading and mixed Rayleigh-Rician fading.

Optimization of Relay Placement in Wireless Butterfly Networks

“…Inspired by the concept of coded cooperation, Vien et al in 2009 [67] also designed a new DSTBC combined with the hybrid automatic repeat request (HARQ) for turbo-coded relay networks to enhance the performance of the DSTBC achieving both diversity gain and coding gain. The STFC in the MIMO systems was also adapted to the cooperative communications where a distributed space-timefrequency block code (DSTFBC) was proposed by Vien et al in 2013 and 2014 [68,69] for non-regenerative cognitive wireless relay networks.…”

“…K. B. Letaief et al design a space-time-frequency block code to exploit spatial diversity for cognitive relay networks with cooperative spectrum sharing [431]. A distributed space-time-frequency block code is further proposed to reduce the detection complexity [432].…”

Quasi‐orthogonal space–frequency and space–time–frequency block codes with modified performance and simplified decoder

“…Recently, space–time–frequency coding has found applications in some other areas of communication systems. For example, in [16, 17], distributed space–time–frequency coding are considered for wireless relay networks. Also, in [18, 19], applications of space–time–frequency coding for multi‐band OFDM and indoor power line channels are considered, respectively.…”
