Performance Evaluation Of Modified V-Blast In Mimo System

摘要

The MIMO system (multiple Antennas at the transmitter and receiver)is a capable of very high theoretical capacities, the most popular architecture is so called vertical VBLAST. V-BLAST is an effective detection method for MIMO communication system, but has large computational complexity due its successive iteration . In this paper we used modified V-BLAST to lessen its computational complexity reducing the number of successive iterations. As a result of this simplification, the computational complexity of the detection is lowered significantly. Simulation results show that the proposed V-BLAST reduces calculation complexity by about 30% while achieving a very close BER performance s the original one
