Windowed multiuser detection techniques are disclosed. A window of data is established, and certain central bits within the window are selected as reliable, while other side bits are ignored. The selected bits are demodulated. The windowed multiuser detector moves along to the next window in such a manner that the next group of central bit decisions lay contiguous with the previous set, and eventually every bit to be demodulated has at some point been a central bit decision. Most any type of MUD algorithm (e.g., MMSE algorithm MUD or M-algorithm MUD) can be used to compute estimates in the windowed data. Unreliable windowed data are distinguished from reliable data (e.g., weighting or other de-emphasis scheme).
