In this paper, the authors investigate different Multiple-Input Multiple-Output (MIMO) receiver structures based on MMSE filtering and Sequential Interference Cancellation (SIC) for the downlink of the 3GPP Long Term Evolution (LTE) system. They divide them into two approaches: symbol-SIC receivers, in which the detection and interference cancellation is done independently for each subcarrier, and codeword-SIC structures, in which the processing is carried out for each independently-coded stream by including the turbo-decoder inside the feedback loop.
