Gaussian approximation of the LLR distribution for the ML and partial marginalization MIMO detectors
14 years 10 months ago
We derive a Gaussian approximation of the LLR distribution conditioned on the transmitted signal and the channel matrix for the soft-output via partial marginalization MIMO detect...
