MIMO-OFDM: Implementation Using Space Time Block Codes (STBC) And V-Blast Technique For Broadband Wireless Communications

Multiple Input Multiple Output (MIMO) technology uses multiple antennas at both the transmitter and receiver ends. Recently, the demand for the use of MIMO systems has increased due to its robustness against Multipath fading and increase in the Spatial Multiplexing Gain and Spatial Diversity Gain. Orthogonal Frequency Division Multiplexing (OFDM) is one of the best digital multiplexing schemes, where signal is divided into number of narrow band channels to obtain spectral efficiency by minimizing the Inter Symbol Interference (ISI). For broadband communications, OFDM transforms a frequency selective channel into a set of parallel flat channels, which reduces the receiver complexity significantly. This article discusses the idea of combined MIMO and OFDM technologies into one, which is implemented through STBC and V-BLAST, where STBC is a Space Time Coding technique and V-BLAST is a detection algorithm developed for MIMO reception. Keywords - BER, Diversity, Fading, MIMO, OFDM, V-BLAST.
