Self and Turbo Iterations for MIMO Receivers and Large-Scale Systems [PDF]
IEEE Wireless Communications Letters, 2019 We investigate a turbo soft detector based on the expectation propagation (EP) algorithm for large-scale multiple-input multiple-output (MIMO) systems. Optimal detection in MIMO systems becomes computationally unfeasible for high-order modulations and/or large number of antennas.
