A low complexity distributed differential scheme based on orthogonal space time block coding for decode-and-forward wireless relay networks

<span lang="EN-US">This work proposes a new differential cooperative diversity scheme with high data rate and low decoding complexity using the decode-and-forward protocol. The proposed model does not require either encoding or channel state information at source node, relay nodes, destination node where sequence is directly transmitted detection method applied nodes node. technique enjoys Furthermore, performance of strategy analyzed by computer simulations in quasi-static Rayleigh fading simulation results show that outperforms corresponding reference strategies.</span>
