LLL Reduction Achieves the Receive Diversity in MIMO Decoding

by Mahmoud Taherzadeh, Amin Mobasher, & Amir K. Khandani arXiv.org E-print Archive, 22 Jan 2006 Diversity order is an important measure for the performance of communication systems over multiple-input multiple-output (MIMO) fading channels. In this paper, we prove that in MIMO multiple access systems, lattice-reduction-aided decoding achieves the maximum receive diversity. Also, we prove that the naive lattice decoding achieves the maximum diversity. Read more
