Abstract :
In this letter, we propose a distributed soft-input soft-output (SISO) coding scheme for a two-way relay network. Novel SISO convolutional encoders are developed and new code design for distributed SISO encoding is derived for the proposed encoder. The simulation results show that our proposed distributed SISO encoding can bring considerable distributed coding gains compared to the conventional soft information forwarding.
