High data rates are a primary concern for wireless system designers today. It is likely that future breakthroughs in wireless communications will be driven mainly by the demand for high data rate applications. Streaming video for example, requires two to three orders of magnitude higher data rates than speech. A simple solution for increasing data rate is to increase channel bandwidth. This however is not usually considered, as it is very costly. Use of Multiple Element Arrays (MEA) at both transmitter & receiver on the other hand can result in the realization of these higher data rates. So far, only partial consideration has been given to the analysis of space-time coding in the practical case of correlated fading.
