Abstract
Initially communication was carried out using analogue signal. Due to its various drawbacks, digital communication was introduced which has so many advantages over analogue communication and soon become very popular. Due to its low cost and easily reachable properties, wireless communication has become popular in communication.In the current scenario of modern wireless communication system, multiple input multiple output (MIMO) technique has emerged as one of the most efficient and significant method. This paper presents an analysis of MIMO system that has been introduced in the wireless communication to increase the diversity and to mitigate the effect of the channel fading phenomenon. In order to provide the transmit diversity, Space Time Block Code (STBC) is used in the Multiple input multiple output system. Effort has been made for deriving the Signal to noise ratio (SNR) and Bit error rate (BER) for different combination of the MIMO wireless communication system. SNR and BER have been computed for different combination of transmit antenna. The results of the simulation suggest that the performance of the MIMO system can be improved by increasing the diversity gain.
