The Design of Two-Dimension Iterative Decoder for Network Coded Cooperation
Combining network code with Cyclic Redundancy Check (CRC), a two-dimension iterative decoder is proposed for network coded cooperation. The decoder organizes the network code as a row decoder, and CRC as a column decoder. The Log-Likelihood Ratios (LLR) of received signal is used as soft information for iterations. The performances are evaluated by the simulations, and its results show that CRC can be used to improve the decoding performance. Recent researches show that network coding in relay-based wireless network has the potential to improve network throughput and robustness.
