Authors(3) :-A. B. Ghadge , S. S. Muttagi, A. A. Bhosale

Multiple Input Multiple Output (MIMO) systems have recently emerged as a key technology in wireless communication systems for increasing both data rates and system performance. There are many schemes that can be applied to MIMO systems such as space time block codes, space time trellis codes, and the Vertical Bell Labs Space-Time Architecture (VBLAST). This paper proposes a MIMO detectors to enhance the performance in MIMO channels. , we study the general MIMO system, the general V-BLAST architecture with Maximum Likelihood (ML), Zero-Forcing (ZF), Minimum Mean-Square Error (MMSE), and Ordered Successive Interference Cancellation (SIC ) detectors and simulate this structure in Rayleigh fading channel. Based on frame error rates and bit error rates, we compare the performance and the computational complexity of these schemes with other existence model. Simulations shown that VBLAST implements a detection technique, i.e. SIC receiver, based on ZF or MMSE combined with symbol cancellation and optimal ordering to improve the performance with lower complexity.
