The combination of multiple-input-multiple-output (MIMO) wireless technology with orthogonal frequency division multiplexing (OFDM) has been recognized as one of the most promising techniques to support high data rate, improved capacity, high performance, and reduced inter-symbol interference(ISI). The broadband channel is a typically non-lineof-sight channel and includes many impairments such as timeselective and frequency-selective fading, due to which MIMO-OFDM serves as a better solution. MIMO-OFDM system has various detection techniques such as ZF (Zero Forcing), MMSE (minimum mean square error), ML (Maximum Likelihood, V-BLAST (Vertical Bell Labs Layered Space-Time). V-BLAST detection undergoes SIC (successive interference calculation) technique which uses spatial multiplexing. This paper mainly focuses on SNR performances based on BER (bit error rate) of received MIMO signals by applying the V-BLAST algorithm. The algorithm was tested on ZF, MMSE, ML detectors at the receiver end of MIMO system with the help of MATLAB simulation. ML was found out to be the best configuration, and BNR improvement of 10 2 and SNR of at least 12dB can be easily achieved.

“…Multiple input multiple output (MIMO) systems offer the potential to obtain a diversity gain and to improve system capacity (Telatar, 1995), (Alamouti, 1998), (Tarokh et al, 1999). Hence the combination of MIMO and OFDM techniques (MIMO-OFDM) is logically widely considered in the new generation of standards for wireless transmission (Boubaker et al, 2001). In these MIMO-OFDM systems, considering coherent reception, the channel state information (CSI) is required for recovering transmitted data and thus channel estimation becomes necessary.…”

“…Moreover, as OFDM allows a frequency selective channel to be considered as flat on each subcarrier, MIMO and OFDM techniques can be well combined. Therefore, MIMO-ODFM systems are now largely considered in the new generation of standards for wireless transmissions, such as 3GPP/LTE [5] [6]. In most MIMO-OFDM systems, channel estimation is required at the receiver side for all sub-carriers between each antenna link.…”
