Abstract	Wireless communication technology employs the application of multiple antennas at both transmitter and receiver sides to improve the data rates through multiplexing or to improve performance through the diversity technique as compared to single antenna systems. In this paper, we studied the BER performance of Maximum Likelihood (ML)-Vertical Bells Lab Layered Space Time Architecture (V-BLAST) Spatial Multiplexing Technique with different modulation techniques such as BPSK and QPSK, in independent identically distributed (i.i.d) flat fading channel like Rayleigh and Ricean Channel. Further, we compared different multiple antenna configuration with BPSK and QPSK modulation techniques in different channel. Finally, we concluded that ML-VBLAST decoding technique using BPSK modulation scheme gives better result than QPSK modulation technique in both the channels. Furthermore, we observed that we obtain optimal result for 1×4 antennas for V-BLAST system in rician fading channel and for Rayleigh channel 4 × 4 antennas for ML-V-BLAST system. Finally, we compared the results of Rayleigh and Ricean Channel for 2 × 2 antenna configurations and we observed that Ricean Channel provide better results as compared to Rayleigh Channel.
