Abstract: A method includes receiving a Code Division Multiple Access (CDMA) carrier carrying at least a pilot channel. Differences are computed between selected soft pilot symbols received on the pilot channel. Based on the computed differences between the selected soft pilot symbols received on the pilot channel, a level of noise is estimated for a data channel that is to be transmitted on the CDMA carrier.

Abstract: A signal processing apparatus to equalize a signal in a multipath channel, where the equalization is based upon forming a correlation vector and the inverse of a covariance matrix, where the covariance matrix is smaller in dimension than the correlation vector. In one embodiment, the signal processing apparatus forms an extended matrix from the inverse of the covariance matrix, equal in dimension to the correlation vector, by selecting one or more rows of the inverse covariance matrix and shifting the selected one or more rows to form the extended matrix. The extended matrix is multiplied by the correlation vector to provide filter weights to the equalizer. In some embodiments, filtering is performed by a sliding window correlator based upon the selected one or more rows of the covariance matrix, followed by filtering based upon the correlation vector.

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 (STAP), interference cancellation multi-user detection (MUD), and combined STAP/MUD techniques. In MUD, 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 MUD techniques provides accurate temporal cancellation of interference with minimal interference residuals. Additional methods and systems extend adaptive signal reconstruction techniques to take Doppler spread into account. STAP techniques permit a wireless receiver to exploit multiple antenna elements to form beams in the direction of the desired signal and nulls in the direction of the interfering signals. The combined STAP-MUD methods and systems increase the probability of successful user detection by taking advantage of the benefits of each reception method. An additional method and system utilizes STAP techniques in the case where no pilot signal is available. This method compares the outputs of various hypothesized STAP solutions.
