Many wireless networks are become part of our daily life. The data rate and range in wireless devices are limited. To overcome this limitation one method is used named MIMO(Multiple input multiple output) is used. Multiple Input Multiple Output (MIMO) systems are wireless systems with multiple antenna elements at both ends of the link. MIMO systems have the ability to exploit, rather than combat, multipath propagation and promise a significant increase in capacity. MIMO communications use multiple antennas at both the transmitter and receiver to exploit the spatial domain for spatial multiplexing and/or spatial diversity. In contrast to spatial multiplexing the purpose of spatial diversity is to increase the diversity order of a MIMO link to mitigate fading by coding a signal across space and time, so that a receiver could receive the replicas of the signal and combine those received signals constructively to achieve a diversity gain. For improving the diversity gain with MIMO OSTBC(Orthogonal Space Time Block Code) . This MIMO OSTBC is used with conventional modulation scheme. Then this system is used using TCM(Trellis Coded Modulation). By using TCM OSTBC MIMO diversity can be achieved higher.
