V-BLAST Detection Algorithm for Spatial Multiplexing Receives with QPSK System
Hirofumi Maruyama, Satoshi Denno, Daisuke Umehara, Masahiro Morikura (Kyoto Univ.) RCS2008-10
Abstract (in Japanese) (See Japanese page) 
(in English) Spatial multiplexing system can offer a high channel capacity.
In spatial multiplexing, the system should have the same number of transmitting antennas and receiving antennas for successful communication.
Our purpose is to propose algorithms for spatial multiplexing decoder which can decode transmitted signals even if the number of transmitting antennas exceeds that of receiving antennas.
In this paper, we propose and evaluate a new algorithm for V-BLAST decoder on QPSK systems.
The algorithm can increase the number of signal streams from transmitting antennas that can be decoded successfully at the same number of receiving antennas.
As a result of this, the algorithm with QPSK systems can expand the transmission capacity.
