Abstract: In this paper, we analyze performance of multi-user(MU)multiple-input multiple-output (MIMO) systems which has emerged recently as an important research topic. In the multi-user MIMO system, downlink and uplink channels are referred to as broadcast channel (BC) and multiple access channel (MAC), respectively. In Broadcast channel data transmission application, the coordinated signal detection on receiver side is mixed with interference. It is very essential to avoid this interference by using different transmission methods at transmitter end. Due to high capacity, increased diversity, and interference suppression; the multi-user MIMO systems are effectively used for broadcast channels applications for efficient data transmission in terms of bit rate at transmitter end and getting maximum signal to noise ratio at the receiver end for next-generation wireless applications. In this paper we compare bit-error rate (BER) and signal to noise ratio (SNR), obtain simulation results and made comparison among different transmission methods which are Channel Inversion (CI), Block Diagnolization (BD), Dirty Paper Coding (DPC) and Tomlinson-Harashima Pre-coding (THP) algorithms.
