The mobile communication systems with data rates more than 1gbps has dramatically increased in recentyears. New techniques are employed to improve the performance of MIMO systems. MIMO systems with multiple antenna elements at transmitter side and receiver side is the promising technology and future for the 4G wireless systems .The techniques that can be applied to MIMO-OFDM systems are V-BLAST and STBC. Space time processing techniques falls into categories such as data rate maximization and diversity gain.In this paper we will compare BER of V-Blast and STBC using BPSK modulation in Matlab version of 2011b.
