Optimized distributed Goppa codes based on spatial modulation

The distributed Goppa coded spatial modulation (DGC-SM) scheme is proposed in cooperative scenarios. In the DGC-SM scheme, relay chooses partial information from source by using idea of selection, and then re-encodes selected information. At destination, a code obtained corresponding to each selection. order get best possible code, an optimal selection algorithm at relay. algorithm, all selections message sequences are considered, which results high complexity. Thus, another optimized with low complexity To further enhance capability information, two efficient joint decoding algorithms called smart improved proposed. Moreover, bit error rate (BER) performance bound derived. Through simulations, effectiveness confirmed. Also, it observed that simulation analytical closely match signal-to-noise ratio (SNR).
