摘要： Systems and techniques relating to image cancellation in received communications signals are described. A described technique includes receiving a communications signal including a desired signal and an image signal; generating a leakage tracing signal at a frequency band of the image signal, the leakage tracing signal including a noise signal, a frequency of the leakage tracing signal being within the frequency band of the image signal; and removing the image signal from a signal that is based on the communications signal and the leakage tracing signal to resolve the desired signal, where the removing is based on an addition of the leakage tracing signal to the communications signal. Removing the image signal can include using one or more weights to control one or more filters to resolve the desired signal. The one or more weights can be determined based on the noise signal.

摘要： Circuitry for providing non-uniform analog-to-digital (“A/D”) signal conversion for wideband signals is provided. The circuitry of the invention is optimized for wideband signals because it does not sacrifice the small-scale resolution of high-probability signal amplitudes while preventing the clipping of low-probability signal amplitudes. The circuitry includes a nonlinear amplifier and an A/D converter that may be uniform or non-uniform. The digital output of the A/D converter may be further processed by circuitry that has an output function that is the inverse of that of the nonlinear amplifier, so as to maintain linear A/D conversion.

摘要： Systems and techniques relating to image cancellation in received communications signals are described. In one aspect, a received communications signal can include a desired signal and an image signal. A leakage tracing signal can be generated, and the image signal can be removed from the communications signal using the leakage tracing signal mixed with the communications signal. Implementations can include generating a first channel signal and a second channel signal, generating a first filter using the first channel signal and the leakage tracing signal, and generating a second filter using the second channel signal and the leakage tracing signal. Removing the image signal from the communications signal can include filtering the first channel signal using the second filter to obtain a first filtered signal, filtering the second channel signal using the first filter to obtain a second filtered signal, and subtracting the second filtered signal from the first filtered signal.
