Abstract
This paper proposes a network coding method with linear mapping and low-complexity estimation for the two-way relay non-reciprocal channel using the M-QAM modulation. The proposed network coding is developed by combining the channel quantization method and linear estimation based on successive interference cancellation. The effect of residual interference due to channel quantization on the signal decision is analyzed in detail in order to understand the system behavior. Analytical and simulation results show that the proposed network coding method can achieve high SER performance and up-link throughput while requiring low computational complexity.
