Abstract

Selective Spanning Fast Enumeration (SSFE) is a promising detection approach for Multiple-Input Multiple-Output (MIMO) systems which allows detection performance to be traded off against computational complexity depending on the communications environment. However, SSFE suffers from two drawbacks: its symbol enumeration strategy cannot properly span modulation schemes of 16 QAM or greater, leading to increased BER, and is computationally inefficient as a result of enumerating redundant symbols. This paper presents Bounded Selective Spanning with Extended Fast Enumeration (BSS-EFE), an adapted SSFE which resolves these issues, avoiding redundant symbol enumeration and enabling increased detection performance and lower complexity for SSFE-based detection systems employing 16 QAM or greater modulation schemes. Experiments show that BSS-EFE this enables to 1 dB BER gain whilst reducing computational complexity up to 16.3% as compared to SSFE.
