Abstract

This paper introduces a novel class of linear soft-input soft-output detectors with boosted communications performance. The detector showed an SNR gain of up to 2.4 dB compared to state-of-the-art linear detectors. We introduce a low-complexity algorithm tailored for VLSI implementation, and propose a suitable architecture. The developed ASIC demonstrates the feasibility and efficiency of the concept, achieving the IEEE 802.11n standard´s peak data rate of 600 Mbit/s.
