Who are the experts? Discuss the case where there a multiple (two) transmit antennas and multiple (two) receive antennas resulting in the formation of a 2x2 Multiple Input Multiple Output (MIMO) channel. . This example shows how hybrid beamforming is employed at the transmit end of a massive MIMO communications system, using techniques for both multi-user and single-user systems. Massive multiple input multiple output (MIMO), well viewed as one of the important techniques for fifth generation (5G) wireless communication, has attracted a great deal of research interest in current years [1-3].The main idea of massive MIMO is to deploy a large-scale number of antennas and employ some simple precoding processing or detection technologies at the base station (BS), which . The simulations were carried out at MATLAB which means keeping the transmitter antenna as two and . Reply. we should be well aware of two facts: 1. directly using maximum a priori (MAP) or MMSE estimation to work with the exact prior degrade the necessity of employing AMP, because achieving a full diversity requires an extremely large set of .
