Systems and methods for adjusting amplitude of an input signal through the application of a gain term are presented. In one embodiment, the gain controller comprises a scaling element that scales the overall signal energy after interference cancellation is performed. This scaling may compensate for overall signal energy reduction resulting from interference cancellation that improves the SNR of the signals of interest. Since prior art receivers typically adjust signal amplitude at the front-end, the gain controller may adjust the amplitude of an interference-canceled signal to a level that is substantially comparable to the level after front-end scaling. The gain controller also comprises a receiving element configured for receiving either an output canceled signal or an uncanceled received signal as an input. For example, the gain controller may receive an interference-canceled signal output from a Coded Signal Processing Engine or a signal with no interfering components removed.

Systems and methods are provided for directionally filtering signals by projecting a received signal onto a subspace substantially orthogonal to selected interfering signals. The received signal typically comprises at least one signal of interest, at least one selected interfering signal, and noise. The received signal may further comprise other signals, including non-selected interfering signals. The projection of the received signal results in substantially no contribution from the selected interference signals on the signal of interest. For example, substantially no residual energy of the selected interference signals remains as an influence on the signal of interest. In one embodiment, a system generates a converted matrix having a substantially orthogonal set of vectors. Each vector may represent one or more selected interfering signals. The vectors may comprise code characteristics of the selected interfering signals.

The present invention provides systems and methods for signal cancellation with a receiver. The receiver comprises a discretizer configured for generating digital signals at different resolutions from a received analog signal. Processing fingers of the receiver generate spreading codes from at least one of the digital signals while a Coded Signal Processing Engine (“CSPE”) substantially cancels interference from at least another one of the digital signals. The spreading codes are transferred to the CSPE where they may be used to construct an interference matrix. One or more cancellation operators may be generated and subsequently applied to the digital signal(s) input to the CSPE to substantially cancel the interference therefrom. The CSPE may adjust the number of bits of the substantially interference cancelled signal(s) to meet a requisite bit width or dynamic range of the receiver. The substantially cancelled signal(s) is then transferred to the processing fingers for further processing.

Systems and methods for searching interference-canceled data are presented. A searcher finger is configured for acquiring a signal that is buried beneath the noise and interference floor due to interference from other signals. The searcher finger can either search for a signal within an uncanceled digital signal or within a substantially interference canceled signal. The substantially interference canceled signal has one or more interfering signals substantially canceled from the digital signal. A Coded Signal Processing Engine is configured for a generating the substantially interference canceled signal by performing signal cancellation on an input signal and transferring the resulting signal to the searcher finger. The searcher finger acquires a signal within the substantially interference canceled signal. The signal cancellation of the processing engine may improve the signal to noise ratio of a signal, which may improve acquisition of the signal by the searcher finger.
