摘要： Various multi-lane ADCs are disclosed that substantially compensate for impairments present within various signals that result from various impairments, such as phase offset, amplitude offset, and/or DC offset to provide some examples, such that their respective digital output samples accurately represent their respective analog inputs. Generally, the various multi-lane ADCs determine various statistical relationships, such as various correlations to provide an example, between these various signals and various known calibration signals to quantify the phase offset, amplitude offset, and/or DC offset that may be present within the various signals. The various multi-lane ADCs adjust the various signals to substantially compensate for the phase offset, amplitude offset, and/or DC offset based upon these various statistical relationships such that their respective digital output samples accurately represent their respective analog inputs.

摘要： A device of dynamic communication of information allows, on the average, non-integer bits per symbol transmission, using a compact code set or a partial response decoding receiver. A stream of selectable predetermined integer bits, e.g., k or k+1 data bits, is grouped into a selectable integer number of bit vectors which then are mapped onto corresponding signal constellations forming transmission symbols. Two or more symbols can be grouped and further encoded, so that a symbol is spread across the two or more symbols being communicated. Sequence estimation using, for example, maximum likelihood techniques, as informed by noise estimates relative to the received signal. Each branch metric in computing the path metric of a considered sequence at the receiver is weighted by the inverse of the noise power. It is desirable that the constellation selection, sequence estimation and noise estimation be performed continuously and dynamically.

摘要： An integrated burst FSK receiver is provided to receive and interpret an RF signal using FSK modulation. The integrated burst FSK receiver uses a programmable RF local oscillator to mix a received signal down to an IF range or baseband, where it is filtered and sampled for subsequent digital processing. Digital filtering and detection are employed to improve overall bit error rate performance and receiver sensitivity. A programmable digital low-pass or band-pass filter can also be used to suppress interference. A matched filter correlator can be used for detection and symbol timing adjustment in one mode, while an adaptive frequency comparator can be used in another mode. Circuits are provided that estimate carrier offset, frequency deviation and signal strength. These measurements can then be used to optimize the receiver performance. A method for receiving and interpreting an RF signal using FSK modulation is also provided.
