Abstract :
In this paper, an improved recursive algorithm for BLAST is proposed. The speedups of the improved recursive algorithm over the original recursive algorithm in the number of multiplications and additions are 1.47 and 1.2 respectively. And the speedups of the improved recursive algorithm over the conventional V-BLAST in the number of multiplications and additions are 1.43M+2.93 and 1.43 M+2.67, respectively, when the number of transmitting antennas is equal to the number of receiving antennas and is M
