Abstract :
User cooperative communication can bring spatial diversity, and improve cell boundary uplink quality. This paper gives a kind of convolutional codes suitable for user cooperation with lower complexity than Turbo codes and LDPC codes, and can guarantee good inter-user communication quality when cooperation succeeds, and also good uplink communication quality when cooperation defeats. Simulation results show that when we use 50% cooperation, under the condition that the two users have similar uplink quality and perfect inter-user channel, at BER = 10-3, this kind of coded cooperation can provide almost 11 dB performance gains, compared with non-cooperation. Moreover, performance of user cooperation using this kind of convolutional codes is better than that using rate-compatible punctured convolutional codes.
