A REVIEW PAPER ON MIMO BASED OFDMA SYSTEM IN DIGITAL COMMUNICATIONS SYSTEM

Abstract: In communication system, the combination of MIMO and OFDMA system is the most promising technology for high bit rate provided for the next generation wireless communication network. This paper presents a review on the structure of MIMO antenna; In MIMO system more than one antenna is used for communication by which capacity and ranged of the system is increased. In MIMO system antennas are used in both transmitter and receiver to improve the communication performance, whereas the OFDMA is the multicarrier multiple access method. MIMO-OFDMA is commonly used for communication system due to its high transmission rates and robustness against multipath fading
