Simulation on performance of space time block code

Abstract

It has been long known that multiple antennas can be used to boost system performance through fading environment. This diversity technique provides the receiver with multiple version of the transmitted signal over independent channel. Therefore the probability of all signals being faded will be less than the probability that just one is faded. This system is often called a multiple-input multiple output (MIMO) system. MIMO uses antenna arrays at both the transmitter and receiver to offer substantial benefits in terms of rate and reliability. Two standards approaches for communicating in MIMO are spatial multiplexing and transmit diversity [1]. Multiplexing sends independent information streams across the transmit antennas to maximize rate while transmit diversity sends redundant information streams to maximize reliability.
