Adaptive DSTBC and Network Coding for TWR Networks in Impulsive Noise Channels

摘要

In the two-way relay (TWR) networks with two relays between two nodes, the previous scheme proposed a TWR network coding system using all Decode-and-Forward (DAF) elements without distributed space time code (DSTBC). In our proposed scheme, we use modieifed Alamouti DSTBC with adapative AAF/DAF elements. The simulation results show that our proposed scheme is better than the previous scheme at 10~(-3) BER by 1.2dB, 1.8dB, 2dB, and 2.2dB for impulsive noise channel parameter δ=2, 1.44, 1, and 0.8, respectively.
