Abstract:
The use of multiple antennas at both transmitter and receiver to formmultiple input and multiple output (MIMO) channels currently hold the potential to drastically improve wireless links spectrum efficiency or robustness, increasing capacity and the ability to increase the transmission speed in future wireless communications system as well as radar. For broadband communications, OFDM turns a frequency selective channel into a set of parallel flat channels, which significantly reduces the receiver complexity.Problems in multipath fading and interference are severe on road condition and environment also so dynamic. Existing wireless system may be utilized single frequency, singleantenna and pulse for multicarrier transmissionand reception. Problems of such system are that in case offailure the total system will become non-operational A distributed system in terms of multicarrier, multiantenna and coded pulse can provide a more suitable communication and sensor give rise toHybrid (SS-OFDM-MIMO) technology is the ultimate solution. The hybrid approach has been essentially been developed for 60GHz frequency provided we have the necessary bandwidth.The performance analysis for the MIMO-OFDM system has been carried out based on MATLAB simulation. The experimental results have been verified using the simulation, the results of simulation have been verified with the various works being carried out in this area and the results conferred to be correct.
