Abstract :
Multi-Source Cooperation (MSC) techniques, including conventional Code Division Multiplexing (CDM) and Classic Network Coding (CNC) are investigated. We adopt a soft sum-product decoding algorithm for the CNC technique and propose a flexible Variable-rate Network Coding (VNC) technique. The iterative decoding convergence of the multiple source computation methods is analysed with the aid of EXtrinsic Information Transfer (EXIT) charts.
