Now-a-days as the people can see that wireless systems are gaining importance in day to day life. These networks have become an essential part of common man's life. The most widely used wireless networks are wireless LAN's, cell phone networks, and other data transfer applications. The main limitations of these wireless devices are the range and data rate. A lot of research has been done to overcome these limitations. One of the technologies is to use Multiple Input Multiple Output (MIMO) system. MIMO along with diversity coding, i.e., Space Time Coding concatenated with channel coding and channel estimation at the receiver can be used to increase the data rate or increase the transmit range without sacrificing the bandwidth or increasing the transmitter power.
