Abstract

Recently, the high-rate data transmission has been one of key issues in wireless mobile communications. MIMO (multiple-input multiple-output) is an emerging technology offering high spectral efficiency with the improved link reliability and interference suppression. In this paper, we introduce the basic concept of space-time code and extend to LST (layered space-time) architecture, especially V-BLAST (vertical Bell-lab layered space-time) system. After that, we express the correlation effect at the receiver. And we simulate the V-BLAST system using various detection algorithm such as ZF (zero-forcing) and MMSE (minimum mean square error) over MIMO channel and analyze the performance according to correlation effect at the receiver
