In this paper, the authors proposed an approximate Gaussian density evolution based MAP decoder for high performance wireless communication. This paper considers a three node (Source (S), Relay (R) and Destination (D)) wireless cooperative communication system, which can be considered as a building block for larger wireless networks. This proposed paper adaptively changes the code and modulation format according to the channel conditions, to improve performance without adding more network cooperation overhead. In proposed architecture, the higher throughput, less power consumption and less area are achieved.
