A modified decoding algorithm of V-BLAST Architecture

In this paper, a new algorithm to simplify the Sphere-decoding of V-BLAST Architecture is deduced. The system Bit Error Ratio (BER) and complexity are simulated to compare the performance when sphere-decoding algorithm is used with the performance when classical sphere-decoding algorithm is used. According to simulation, the complexity of the modified sphere-decoding algorithm is much lower than the complexity of classical sphere-decoding.
