Abstract:
A novel reduced-complexity soft-input soft-output minimum mean square error detection algorithm for MIMO systems together with an area-throughput efficient VLSI architecture is described. A detailed comparison to related work is presented. The proposed VLSI architecture of the novel algorithm represents — to the best of our knowledge — the most areathroughput efficient SISO MIMO detector ASIC reported so far, being 2.3x more efficient than its best competitor. It achieves a throughput of up to 923 Mbit/s and occupies down to half of the competitor’s area while sustaining the IEEE 802.11n standard’s peak data rate.
