Implementation and Performance Analysis of Multiuser Detector for Massive MIMO OFDM System over Rayleigh Channel

摘要

The Massive Multiple Input Multiple Output system using Orthogonal Frequency Division Multiplexing is emerging as a promising technique for future high data rate wireless communication. As the number of antennas at transmitter and receiver increases, major advantage is that spectral efficiency can be improved. The fading may be effectively reduced because of the increased achievable diversity by Massive MIMO. Multiuser Detector for Massive MIMO OFDM model is implemented and its performance is analyzed. Symbol Error Rate, Bit Error Rate and outage probability of the multiuser detector are simulated and might be inferred that the performance will be enhanced as compared to MIMO OFDM. The radiation patterns of both the transmitter and receiver antennas are plotted and it can be substantiated that the output power radiated by the multiuser detector at the base station is radiated as desired in cellular wireless communication.
