A lattice-reduction-aided MIMO receiver with virtual channel detection

In this paper, we propose a lattice-reduction-aided MIMO receiver with virtual channel detection. The proposed receiver provides high-speed data transmission in downlink mobile communications by using lattice-reduction and a concept of virtual channel to increase the number of multiplexed signal streams that can be detected at the receiver. Numerical simulation shows that the receiver achieves bit error rate of 10^-4 at E_b/N₀ of 30 dB, even when 8 signal streams are received by 2 antennas without any error correction coding.
