Abstract:

To reduce decoding delay of a communication scheme which is backward-decoding-based and achievable Chong-Motani-Garg capacity bounds, a novel forward-sliding-window decoding-based communication scheme is proposed.In this scheme, if w=(w₁1, w₂2)is the message to be sent in block b, the relay will decode message w₁ and generate a new message z at the end of block b, and the receiver will decode message w₁ at the end of block b+1 and decode message z and w₂ at the end of block b+2.Analysis results show that this new communication scheme can achieve the same Chong-Motani-Garg bounds and the decoding delay is only two blocks which is much shorter than that of backward decoding.Therefore, Chong-Motani-Garg bounds can be achieved by a forward decoding-based communication scheme with short decoding delay.
