Fixed-point Implementation of Approximate Message Passing (AMP) algorithm in massive MIMO systems

Fixed-point Implementation of Approximate Message Passing (AMP) algorithm in massive MIMO systems

In massive multiple input and multiple output (MIMO) systems the challenge is the detection of the individual signals from the composite signal with a large system limit. The optimal detector becomes prohibitively complex. The approximate message passing (AMP) algorithm, designed for compressed sens...
