Algorithms and Architectures of Energy-Efficient Error-Resilient MIMO Detectors for Memory-Dominated Wireless Communication Systems
2014
IEEE Transactions on Circuits and Systems Part 1: Regular Papers
Preserved Fulltext
In this paper we present the algorithm and VLSI architecture of a novel error-resilient K-Best MIMO detector based on the combined distribution of channel noise and induced errors due to VoS. ...
Furthermore, based on experimental results, when jointly considering the detector and memory power consumption, the proposed resilient scheme with VoS memory can achieve up to 32.64% savings compared to ...
As a result, it can be concluded that the proposed error-resilient MIMO detectors can operate more reliably under reduced supply voltages, with reduced power consumption as shown in Table II . ...
