A VLSI architecture of the Schnorr-Euchner decoder for MIMO systems

Guo, Zhan and Nilsson, Peter LU (2004) Proceedings of the IEEE 6th Circuits and Systems Symposium on Emerging Technologies: Frontiers of Mobile and Wireless Communication 1. p.65-68
Abstract
The lattice decoder is shown to approach the performance of Maximum-likelihood decoder for MIMO wireless systems with low complexity. A VLSI architecture of the K-best Schnorr-Euchner lattice decoder is proposed in this paper. The architecture is optimized on both algorithm and architecture levels, and supports a dynamic range of SNR [less-than or equal to] 30 dB. Compared to a conventional VLSI implementation of the lattice decoder for MIMO systems, the proposed architecture results in up to 37% computation reductions, 20% area savings and more than 5 times decoding throughput improvements. The proposed architecture is implemented with 0.35 μm technology for a system of 4 transmit/receive antennas and 16-QAM modulation. The results show... (More)

A VLSI architecture of the K-best Schnorr-Euchner lattice decoder is proposed in this paper.

Compared to a conventional VLSI implementation of the lattice decoder for MIMO systems, the proposed architecture results in up to 37% computation reductions, 20% area savings and more than 5 times decoding throughput improvements. The proposed architecture is implemented with 0.35 μm technology for a system of 4 transmit/receive antennas and 16-QAM modulation. The results show that a decoding throughput of 53.3 Mbits/s can be achieved, and the decoding latency is less than 2.5 μs. © 2004 IEEE. (Less)
