In this paper, we present a new efficient algorithm for detecting such architectures with respect to the MMSE criterion. This algorithm utilizes a sorted QR decomposition of the channel matrix and leads to a simple successive detection structure. The algorithm needs only a fraction of computational effort compared to the standard V-BLAST algorithm and achieves the same bit error performance.}, booktitle={IEEE 2003 Global Telecommunications Conference (Globecom 2003)} }
