Abstract:

A cooperative protocol termed as fractional incremental relaying (FIR) is firstly presented to achieve higher spectral efficiency for wireless communications. In FIR protocol, when direct transmission of a packet fails, the relay node divides the received packet into several subblocks and transmits one by one as needed instead of the entire packet. Both analysis and simulation demonstrate that the proposed FIR protocol can achieve less average transmission duration and higher spectral efficiency than the traditional incremental relaying protocol does.

Key words: cooperative communication, incremental relaying, partial retransmission, performance analysis
