Abstract
Multiple Input Multiple Output (MIMO) systems form an essential part of LTE in order to achieve the striving requirements for throughput and system robustness. In Long Term Evolution (LTE), MIMO technologies have been broadly used to get better downlink peak rate, cell coverage, as well as average cell throughput. To achieve these goals, LTE adopts two major MIMO technologies i. e. Spatial multiplexing (SM) and transmit diversity (TD) to offer substantial benefits in terms of rate and reliability. There is an optimal tradeoff between Diversity and spatial Multiplexing gain, which is indication of rate and probability of error. This paper will show throughput and Bit error rate performance with specific application to SM and TD in 2X2 LTE Correlation based channel environments. The effect of different environment conditions using correlation 2x2 MIMO channel model is determined describing how they relate to SNR and vehicular speed at LTE Receiver . The investigations reported in this paper helps in estimating the optimum switching conditions between two MIMO approaches for fixed antenna spacing at transmitter and receiver.
