A Maximum Logarithmic Maximum a Posteriori Probability Based Soft-Input Soft-Output Detector for the Coded Spatial Modulation Systems

Soft-input soft-output (SISO) detector for the iterative detection and decoding of coded spatial modulation (SM) signals needs to compute the extrinsic bit log-likelihood ratio (LLR) associated with each detected bit. The maximum logarithmic maximum a posteriori (max-log-MAP) detector is known to pe...
