BIT ERROR AND DATA TRANSMISSION RATE AUGMENTATION THROUGH MIMO DIVERSITY TECHNIQUE

Mobile network systems have experienced exponential growth and the demand for improved quality in terms of data rates, information integrity and coverage force for a better mobile network technology for the coming era. In this research article, different cooperative relay schemes were analyzed which constructively forward signals such that wireless network capacity, throughput and coverage is extensively improved. Incremental relaying protocol is proposed for better spectral efficiency. The systems are analyzed under Rayleigh fading channel and for data integrity at destination turbo encoding at transmitter node and relay node and turbo decoding at relay node as well as destination node were used. The error probability and data rate is further optimized by using multiple-input and multiple-output diversity technique on basis of alamouti scheme. From the results it was noted that, the cooperative relaying mode outperforms the non-cooperative systems in terms of performance of the bit error rate
