Abstract
Due to the increased demand of wireless communication systems because of the features of the system which provides a wide coverage, high throughput and reliable services, the MIMO systems communication has come into existence and has been shown to be one of the most promising emerging wireless technologies that can efficiently boost the data transmission rate and capacity of wireless communication system. An effective and practical way to approach these demands of MIMO wireless channel is to employ Space Time (ST) Coding. The performance improvement of MIMO systems can be assessed by using diversity gain and spatial multiplexing gain. Space Time Coding transmits signal across the spatial and time domain simultaneously in order to achieve diversity gain without increasing bandwidth. In this paper, we exploit the space and time diversity to decode the quasi and rotated quasi orthogonal space time block codes (QOSTBC) based on Jakes model and Dent channel model. For Doppler shifting and Rayleigh distribution we make use of dent channel model. This provides fast decoding and gives better performance of communication system as compared to Jakes model. BER analysis has been presented in terms of diversity and code rate.
