Here a simple MRC based Detection method for Massive MIMO is given. In general the Massive MIMO has system model with (Nt != Nr)Asymmetrical case, (Nt = Nr) Symmetrical case. Various MIMO detectors(Linear(ZF, MMSE), Nonlinear(OSIC)) can be used for transmitted data detection. Some of the example codes for some well known detectors are given here for reference.
Some of the Massive MIMO Detectors are
(1) Maximal Ratio Combining (MRC) based Detector for Asymmetrical Massive MIMO.
(2) Tabu search method for Symmetric Massive MIMO detector.
(3) QR-OSIC based Symmetric Massive MIMO detector.
