Wireless systems with high data rate and short code durations typically encounter unacceptable inter-symbol interference (ISI) due to multipath propagation and its inherent delay propagation. Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier-based ISI mitigation technology that increases the power of a wireless system through spectral efficiency. In this paper, the OFDM system has been studied and combined with the multiple input multiple output (MIMO) technology that doubles the transmission speed and then improves the new system called MIMO-OFDM using Vertical-Bell Laboratories Layered Space-Time (V-BLAST), which works to reduce the error rate of the bits, which in turn contributed greatly to the increase in channel capacity
