Abstract

Collaborative reception has been proposed to improves the frequency utilization efficiency in wireless networks. This paper proposes a novel iterative noise cancelling receiver with soft-output lattice reduction (LR)-aided detector, which improves further frequency utilization efficiency. The proposed receiver achieves near optimum performance by removing an equivalent noise generating in the MMSE filtering. Moreover, the proposed detector in the receiver calculates a log likelihood ratio as a soft-output without exhaustive search even though the LR is applied. The soft-information enables the proposed receiver to improve the transmission performance, furthermore. Because the proposed receiver does not have non-linear signal processing, apparently, the proposed receiver can be implemented with low computational complexity. The performance is confirmed by computer simulation.
