A communication method is proposed using Minimum Mean Square Error (MMSE) precoding

and Successive Interference Cancellation (SIC) technique for millimetre-wave multiple-input

multiple-output (mm-Wave MIMO) based wireless communication system. The mm-Wave MIMO

technology for wireless communication system is the base potential technology for its high data transfer

rate followed by data instruction and low power consumption compared to Long-Term Evolution (LTE).

The mm-Wave system is already available in indoor hotspot and Wi-Fi backhaul for its high bandwidth

availability and potential lead to rate of numerous Gbps/user. But, in mobile wireless communication

system this technique is lagging because the channel faces relative orthogonal coordination and multiple

node detection problems while rapid movement of nodes (transmitter and receiver) occur. To improve

the conventional mm-wave MIMO nodal detection and coordination performance, the system processes

data using symbolized error vector technique for linearization. Then the MMSE precoding detection

technique improves the link strength by constantly fitting the channel coefficients based on number of

independent service antennas (M), Signal to Noise Ratio (SNR), Channel Matrix (CM) and mean square

errors (MSE). To maintain sequentially encoded user data connectivity and to overcome data loss, SIC

method is used in combination with MMSE. MATLAB was used to validate the proposed

system performance.
