MIMO-OFDMA (Multiple Input Multiple Output-Orthogonal Frequency Division Multiple
Access) resource allocation is studied in this paper. The considered problem is to provide eachuser with more data rates in wireless communication system by using the suitable value of bandwidth. The objective of this research is to focus on how to improve the data rate by using efficient bandwidth in MIMO-OFDMA system. The different diversity techniques are also applied to observe which technique is the best for the achievement of maximum diversity order.The simulations show that the space time frequency (STF) diversity technique achieves the highest diversity order by achieves more than 50 percent improvement compared to the system without diversity method, and the value of suitable bandwidth is identified to improve the transmission rate of the system.
