| 20080272813 | Analog To Digital Converter Clock Synchronizer - The present application generally relates to apparatuses such as television signal processing apparatus that process radio frequency signals. More specifically, the present application is particularly useful in integrated circuits that must receive a radio frequency signal and simultaneously use circuitry where the timing of the operations are based on the received RF signal and circuitry where the timing is based on a fixed rate signal with sensitivity to clock jitter. According to an exemplary embodiment, the apparatus comprises, a first input (RefClk), a second input (PllClk), an output (CLK | 11-06-2008 |
| 20100020235 | Co-channel interference remover - A receiver (a) translates a frequency spectrum of a received wideband signal such that a narrowband region of the wideband signal is applied to a filter for use in removing narrowband interference; and (b) tracks the narrowband interference by adjusting the frequency translation as a function of signal levels in narrowband regions adjacent to the narrowband interference region. | 01-28-2010 |
| 20100029235 | Co-channel interference detector - A receiver searches for and identifies the locations of narrowband interference by sweeping across a wideband frequency channel to measure power levels of at least three narrowband frequency regions and determines if at least one interfering signal is present as a function of the measured power levels. | 02-04-2010 |
| 20100289965 | EQUALIZER BASED SYMBOL TIMING RECOVERY WITH SYMBOL ENABLED CONTROL - A receiver is an ATSC (Advanced Television Systems Committee)-receiver and comprises a controller and an equalizer, which comprises a feed-forward filter and a feed-back filter. The feed-forward filter comprising at least one tap associated with at least one tap coefficient value. The controller determines a location of at least one tap of the equalizer; and if that location is close to a tap boundary (or edge) of the equalizer, the at least one tap of the equalizer is shifted forward or backward by at least one sample position. | 11-18-2010 |
| 20110069747 | METHOD AND APPARATUS FOR DETERMINING CHANNELS IN A SIGNAL - The determination and identification of channels in a signal is an important aspect of the operation of a signal receiver. A method ( | 03-24-2011 |
| 20110074500 | APPARATUS AND METHOD FOR DETERMINATION OF SIGNAL FORMAT - The determination of the signal modulation format for a channel is an important aspect of the operation of a signal receiver. A method ( | 03-31-2011 |
