Patent number: 9042436Abstract: 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.Type: GrantFiled: March 26, 2013Date of Patent: May 26, 2015Assignee: Broadcom CorporationInventors: Bruce J.

Patent number: 9008248Abstract: Systems and methods for demodulating a plurality of contiguous channels contained within a bandlimited portion of a radio-frequency (RF) input signal are provided. In an embodiment, the bandlimited portion of the RF input signal is down-converted to baseband. After down-conversion, the bandlimited portion overlaps at baseband with a mirror image of the bandlimited portion. The plurality of contiguous channels within the down-converted signal similarly overlap at baseband and subsequently occupy a bandwidth substantially equal to half that required before down-converting. Image rejection is performed in the digital domain to recover each of the plurality of overlapping channels.Type: GrantFiled: September 3, 2009Date of Patent: April 14, 2015Assignee: Broadcom CorporationInventors: Francesco Gatta, Ramon Gomez, Leonard Dauphinee, Young Joon Shin, Hanli Zou, Massimo Brandolini, Giuseppe Cusmai

Patent number: 8208530Abstract: An apparatus and method for correcting IQ imbalance are presented. An exemplary receiver for processing I and Q signals from a tuner includes: a non-decision directed (NDD) imbalance canceller coupled to receive the I and Q signals, and a decision directed (DD) imbalance canceller coupled to the non-decision directed imbalance canceller. The DD imbalance canceller converges after the NDD imbalance canceller converges, so as to correct IQ imbalances in the receiver. An exemplary method for processing I and Q signals from a tuner includes: (a) converging a NDD imbalance canceller to correct a majority of IQ imbalances, and (b) subsequently converging a DD imbalance canceller to correct a remainder of IQ imbalances not corrected in step (a). The apparatus and method correct frequency-dependent and frequency-independent IQ imbalances.Type: GrantFiled: January 19, 2006Date of Patent: June 26, 2012Assignee: Broadcom CorporationInventors: Loke Tan, Hanli Zou, William Ngai
