International Classification:

H03H 7/30

US Classification:

375229, 375232, 375233, 375230, 370495, 370503

Abstract:

An apparatus is disclosed to compensate for non-linear effects resulting from the transmitter, the receiver, and/or the communication channel in a communication system. A receiver of the communication system contains an image cancellation module that compensates for images generated during the modulation and/or demodulation process. The image cancellation module includes a fine carrier correction loop to correct for frequency offsets between the transmitter and receiver. The image cancellation module includes a coarse acquisition mode and a decision directed mode. The decision directed mode allows for a larger signal-to-noise ratio for the receiver when compared against the coarse acquisition mode.

International Classification:

H03M 1/12

US Classification:

341155, 341132, 341139, 341158, 341159

Abstract:

A method and apparatus is disclosed to extend a dynamic input range of an analog to digital converter (ADC). A composite ADC may include one or more ADCs. The one or more ADCs compare a signal metric of an analog input signal to quantization levels to produce intermediate digital output signals using one or more non-clipping input values. The composite ADC may select among the one or more intermediate digital output signals based on the signal metric of the analog input signal to produce a final digital output.

International Classification:

H04N 7/12
H04N 11/02

US Classification:

37524026

Abstract:

A method and apparatus is disclosed to map a sequence of data to Quadrature Amplitude Modulation (QAM) constellation symbols. The method and apparatus encodes only a portion of the sequence of data and leaves a remaining portion of the sequence of data unencoded. The encoded portion of the sequence of data and the remaining unencoded portion of the sequence of data are then mapped into modulation symbols of the QAM constellation. The encoded portion of the sequence of data selects subsets of the QAM constellation, and the remaining unencoded portion of the sequence of data determines a specific modulation symbol within each subset of the QAM constellation.

International Classification:

H03M 1/06

US Classification:

341118, 341155

Abstract:

A method and apparatus is disclosed to compensate for impairments within a data converter such that its output is a more accurate representation of its input. The data converter includes a main data converter, a reference data converter, and a correction module. The main data converter may be characterized as having the impairments. As a result, the output of the main data converter is not the most accurate representation of its input. The reference data converter is designed such that the impairments are not present. The correction module estimates the impairments present within the main data converter using its output and the reference data converter to generate corrections coefficients. The correction module adjusts the output of the main data converter using the corrections coefficients to improve the performance of the data converter.
