An enhanced transmission rate with efficient bandwidth using diversity technique for OFDMA resource allocation / Muhammad Husaini Ghazali

MIMO-OFDMA (Multiple Input Multiple Output-Orthogonal Frequency Division Multiple Access) resource allocation is studied in this paper. The considered problem is to provide each user with more data rate in wireless communication system. The objectives of this research focus on transmission rate on how to maintain or increase the data rate with efficient bandwidth. Diversity technique is also applied to see which one is the best for maximum achievement diversity between space time diversity, space frequency diversity and space time-frequency diversity. The simulation will show which technique will achieve the maximum diversity order in MIMO-OFDMA system and the suitable bandwidth to improve transmission rate.
