With increasing technology many new techniques are coming with which we can improve today's available techniques for better future. In this project we are trying to show new communication technique using multiple inputs and multiple outputs (MIMO). With MIMO we are using orthogonal frequency division multiplexing (OFDM) which is useful in sending large amount of data in single frequency band. MIMO can be used with high data rate and reduced distortion with V-BLAST technique.In MIMO communication system V-BLAST, D-BLAST and Alamati methods are used to improving bit error rate and signal to noise ratio. So In this project I am using V-BLAST and DBLAST algorithms and develop code using BPSK modulation system. For V-BLAST processing algorithms and CCI cancellation has two types of equalizers zero forcing (ZF) and Minimum Mean Square Error (MMSE). For project we use MMSE equalizer using Rayleigh channel.
