Abstract
Methods and systems in a wireless receiver for enabling the reception of input signals at varied power levels in the presence of co-channel interference utilizing combinations of space-time adaptive processing, interference cancellation multi-user detection, and combined techniques. In multi-user detection, code, timing, and possibly channel information of multiple users are jointly used to better detect each individual user. The novel combination of adaptive signal reconstruction techniques with interference cancellation techniques provides accurate temporal cancellation of interference with minimal interference residuals.
