Large MIMO Systems: A Low-Complexity Detector at High Spectral Efficiencies

Abstract: Abstract-We consider large MIMO systems, where by 'large' we mean number of transmit and receive antennas of the order of tens to hundreds. Such large MIMO systems will be of immense interest because of the very high spectral efficiencies possible in such systems. We present a low-complexity detector which achieves uncoded near-exponential diversity performance for hundreds of antennas in V-BLAST (i.e., achieves near SISO AWGN performance in a large MIMO fading environment) with an average per-bit complexity o… Show more

“…Given the limitations of existing algorithms, new approaches to evaluating massive MIMO systems are required to provide meaningful, rather than merely theoretical, results illustrating the benefit of such networks. Research on massive MIMO links ranges from informationtheoretic analyses of asymptotic antenna growth [32]- [34] to applications of well-known communications schemes such as multicarrier CDMA [35] or V-BLAST [36] to MIMO systems with up to 600 transmit and receive antennas. The work in [2] identifies various practical concerns associated with large arrays and develops transmission and reception schemes for massive MIMO that require low complexity and low power.…”
