This paper deals with asynchronous cooperative relay network utilizing coded distributed closed-loop extended orthogonal space time block coding (CL EO-STBC) at the relay nodes to achieve full cooperative diversity and unity data transmission rate between the relay nodes and the destination node with coding gain and linear decoding complexity for the cases of four relay nodes. Parallel interference cancellation (PIC) detection is applied at the destination node to combat intersymbol interference (ISI) generated for the asynchronous among the relay nodes. Furthermore, pairwise error probability (PEP) analysis is used to confirm the available cooperative diversity. End-to-end bit error rate (BER) simulations with and without outer coding are utilized to confirm the efficacy of the scheme.
