Abstract

Lattice reduction (LR) based detectors has been investigated for multiple input multiple output (MIMO) systems. For most LR aided detectors, it is assumed that the channel matrix is a square or tall matrix. However, practically there are many cases that the channel matrix is fat which is referred to as the underdetermined/rank-deficient MIMO system. In this paper, we employ the pre-voting cancellation approach and propose the LR-based detectors for underdetermined MIMO systems. It can be shown that the proposed detectors can exploit a full receive diversity. Furthermore, the pre-voting vector selection criteria for the proposed detectors are taken into account to improve performance further.
