MOBILE WIMAX SYSTEM’S COMPUTER SIMULATION AND FIELD EXPERIMENT FOR DOWNLINK MULTIUSER MIMO

This paper of Computer Simulation and Field Experiment for Downlink Multiuser MIMO in Mobile WiMAX System overviewed the Current issues regarding the WiMAX System of today. The transmission performance for a downlink mobile WiMAX system with multiuser multiple-input multiple-output (MU-MIMO) systems in a computer simulation and field experiment is described. We Can Say that In computer simulation, a MU-MIMO transmission system can be realized by using the block diagonalization (BD) algorithm, and each user can receive signals without any signal interference from other users. The Paper is explaining the major contents regarding the the bit error rate (BER) performance and channel capacity in accordance with modulation schemes and the number of streams were simulated in a spatially correlated multipath fading environment. Furthermore, paper propose a method for evaluating the transmission performance for this downlink mobile WiMAX system in this environment by using the computer simulation Effectively the major issue of It was confirmed that the experimental mobile WiMAX system for MU-MIMO transmission successfully increased the total channel capacity of the system.
