Based on the CMA, a proved blind multiuser detection, which combined with the multistage wiener filter(MSWF) for UWB systems in a realistic indoor channel is proposed in this paper. This new algorithm had a low computational complexity without the computation of matrix inverse. The proposed MSWF+CMA receiver is shown to have simpler computational complexity per weight update and faster convergence...
A blind multiuser receiver is proposed for multiuser detection of UWB systems in a realistic indoor channel. The proposed blind multiuser receiver is based on the constant-modulus algorithm (CMA), which is known to provide satisfactory performances in a blind setting. In order to overcome the CMA interference capture problem typical of a multiuser scenario, we propose to adopt a two stage receiver:...
