Design of joint network-channel coding based on Turbo code and its performance analysis

According to idea of joint network-channel coding, a scheme of joint network-channel coding based on Turbo code applied to multiple access relay channel was proposed, and implementation of relay node encoding and base station decoding was introduced in details. The simulation of the scheme was compared with the point to point scheme and XOR operation network-channel coding scheme. The simulation results show that the scheme can sufficiently use additional redundancy from the relay channel, and significantly improve performance of wireless communication systems.
