Abstract
BLAST (Bell Laboratories layered space-time) wireless systems are multiple-antenna communication schemes which can achieve very high spectral efficiencies in scattering environments, with no increase in bandwidth or transmitted power. The most popular and, by far, the most practical architecture is the so-called vertical BLAST (V-BLAST). The signal detection algorithm of a V-BLAST system is computationally very intensive. If the number of transmitters is M and is equal to the number of receivers, this complexity is proportional to M4 at each sample time. In this paper, we propose a simple and very efficient algorithm that reduces the complexity by a factor of M.
