摘要： A multistage linear receiver for extracting data embedded in a received spread-spectrum signal having a plurality of channels using a direct sequence code division multiple access system. The multistage receiver comprises an initial plurality of spread-spectrum detectors, a plurality of detector weighting devices, a first plurality of product devices, a first combiner, a first plurality of spread-spectrum detectors, a first plurality of weight-product devices and an output combiner. The initial plurality of spread-spectrum detectors despreads and delays the plurality of channels to generate a plurality of detector-output signals. The detector weighting devices weight the plurality of detector-output signals with a plurality of detector weights as a plurality of weighted-detector signals. The plurality of detector-output signals are spread-spectrum processed by the first plurality of product devices to generate a first plurality of spread-spectrum signals which are combined by the first combiner as a first combined signal. The first plurality of spread-spectrum detectors despreads and delays the first combined signal as a first plurality of despread-combined signals which are weighted by the first plurality of weight-product devices to generate a first plurality of weighted signals. The output combiner combines the first plurality of weighted signals and the plurality of weighted-detector signals to extract the data. Additional stages comprising product devices, combiners and weight-product devices may be added as necessary or desired.

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： 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.
