Abstract

This paper proposes a novel low complexity lattice reduction-Aided iterative receiver for overloaded MIMO. Novel noise cancellation is proposed that increases an equivalent channel gain with a scalar gain introduced in this paper, which results in the improvement of the signal to noise power ratio (SNR). The performance of the proposed receiver is theoretically analyzed that the lattice reduction guarantees the SNR of the detector to be more than a value proportional to the scalar gain, when the LenstraLenstraLovas (LLL) algorithm is applied to implement the lattice reduction. The proposed receiver attains a gain of about 5dB at the BER of 10 -4 in a 6 × 2 overloaded MIMO channel.
