摘要： A system to decode a multirate CDMA signal. In one aspect the system includes a high rate detector to generate high rate outputs based upon decoding an input signal that includes high rate users and low rate users. The high rate outputs include actual high rate users and effective high rate users. A second stage applies a first linear transformation to the high rate outputs to generate second stage outputs. A third stage applies a second linear transformation to the second stage outputs to generate decoupled low rate user outputs and decoupled actual high rate user outputs.

摘要： 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.

摘要： Estimates of interference from co-channel pilot signals from one or more base stations may be formed at a receiver and subtracted out from the received signal to improve the detection of a desired signal. The complexity of pilot interference cancellation may be reduced by selecting only particular crosscorrelation terms to be estimated and processed. The remaining terms or crosscorrelation values may be eliminated from the computation, reducing computational complexity. In addition, selection decisions may be stored to reduce the need to excessively reevaluate the selection decision.

摘要： 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.
