Abstract:

To analyze the performance of cooperative automatic repeat request (CARQ) network, which adopts equal gain combining over Nakagamim channels, an approximation strategy is utilized to derive frame error probability at high signaltonoise ratio. It is applied for the networks with arbitrary relay number. Simulations verify the reliability of the theoretical analysis and the superiority of CARQ when compared with traditional automatic repeat request （ARQ）. 

Key words: cooperative automatic repeat request, equal gain combining, relay
