The next generation of broadband wireless communication system is expected to provide user with wireless multimedia services such as high-speed internet access, wireless television and mobile television. Multiple input and multiple output (MIMO) can be a solution for such demands. In MIMO systems, multiple antennas at both transmitter & receiver and diversity techniques can be used to reduce multi-path fading and interference. But transmit diversity scheme are growing increasingly popular as they promise high data rate transmission over wireless fading channels in both the uplink and downlink while putting the diversity burden on the base station and the coding schemes like space time block coding and space time trellis coding are explored, out of which space time block codes provide full diversity with no coding gain and space time trellis coding provides full diversity and coding gain with complex receivers. This paper presents the design of a MIMO system which takes advantage of both these coding schemes
