MIMO INTERFERENCE AND PATH LOSS REDUCTION USING ADAPTIVE ANTENNA SYSTEM ALONG WITH OPTIMIZATION OF FREQUENCY FOR ZERO PATH LOSS

Abstract:

Wireless communication technology is used by almost everyone now a day, so a large number of users can be handled by the wireless communication system where Multiple Input & Multiple Output (MIMO)technology is used. The main problems of MIMO are interference due to a large number of users and path loss due to traverse of information or signal through the medium. The solutions of above-mentioned problems are discussed here. The path loss is calculated at the receiver by standard model and the inverse of those attenuations are calculated and path losses are eliminated at the receiver by Adaptive Antenna Technology (AAT). The attenuation is also reduced by optimize slope method (OSM) where attenuation is eliminated by maintaining a frequency to distance ratio by varying the frequency. By using standard CDMA technology, the problem of interference is also addressed.
