A Low Complexity QR-based Selection Criterion for MIMO Precoding

摘要：

This paper proposes a simplified QR-based selection criterion for the efficient optimization of multiple-input multiple-output (MIMO) precoding in a limited feedback system. The proposed selection criterion is developed which determines the precoder yielding the maximum of minimum diagonal entries of the upper triangular matrix of the QR-decomposition on the MIMO channel. Performance evaluation via computer simulations shows that the proposed QR-based precoding scheme optimizes detection performance with low-complexity compared to existing schemes.
