Abstract :
We propose an adaptive Turbo multiuser detection and co-channel interference (CCI) suppression scheme for the uplink single-carrier frequency division multiple access (SC-FDMA) system, with multiple antennas employed for both each user and the base station. Turbo detection is incorporated with the simplified Turbo recursive- least-square (RLS) channel estimator, which provides close performance to the case with perfect channel state information (CSI). To suppress unknown CCI, we design a block-wise estimator, based on low pass smoothing, to estimate the spatial correlation matrix of unknown CCI plus noise.
