Abstract

Equalization for uplink MIMO SC-FDMA LTE multi-stream transmission is considered utilizing linear filtering methods and redundancy in the form of channel coding. The equalizer jointly removes inter-symbol (ISI) as well as spatial (MIMO) interference. It is observed that in an unequal received power situation, gains over traditional MMSE frequency equalization can be obtained via group-based cancellation with turbo equalization. It is shown that signal co-existence is possible with this methodology and therefore QoS for cell-edge users can be maintained at considerably higher noise levels as compared to a baseline receiver.
