Review on STBC coded MISO and MIMO in Frequency Selective Wireless Fading Channel

Abstract

Diversity methods offer the receiver with separately faded copies of the transmitted signal with the expectation that at least one of these replicas will be received properly. There are ranges of techniques available during which these faded copies can be recovered and used as part of preparations for better reception. Transmit diversity uses multiple transmit antennas to offer the receiver with multiple uncorrelated replicas of the transmitted signal. The advantage is that the difficulty of having multiple antennas is located on the transmitter, which can be common among many receivers for the downlink of a wireless system, even as still providing diversity benefits. This technology is called as MIMO system. Hence the multipath fading channels are measured as an advantage scenario in MIMO. This is the most preferred technique in fourth generation cellular communication, as higher data rates can be achieved. Our objective is to review concatenating various error control codes in the MIMO setting using BER and EDR as performance indicators.
