| 20100283903 | PSEUDO TONE-BASED SYMBOL TIMING RECOVERY AND CARRIER TRACKING LOOP DETECTORS FOR VESTIGIAL SIDEBAND RECEIVERS - A receiver is an ATSC (Advanced Television Systems Committee)-receiver and comprises a pseudo-tone based carrier tracking loop and symbol timing recovery loop comprising one, or more, detectors for providing at least two pseudo tone (PST) signals. The first PST signal drives the carrier tracking loop and the second PST signal drives the symbol timing recovery loop. The detector provides the first PST signal such that the first PST signal is determined as a function of carrier offset excluding symbol-timing offset; and provides the second PST signal such that the second PST signal is determined as a function of symbol timing offset excluding carrier offset. | 11-11-2010 |
| 20100283909 | DECOUPLED DATA-AIDED CARRIER TRACKING LOOP AND SYMBOL TIMING RECOVERY LOOP - A receiver is an ATSC (Advanced Television Systems Committee)-receiver and comprises a staggered quadrature amplitude modulator for providing an staggered quadrature amplitude modulated (SQAM) signal from a received signal; an equalizer and a data-aided symbol timing recovery (STR) loop. The equalizer operates outside of the data-aided symbol timing recover loop. | 11-11-2010 |
| 20100283910 | DECOUPLED DATA-AIDED TIMING AND CARRIER TRACKING LOOP - A receiver is an ATSC (Advanced Television Systems Committee)-receiver and comprises a staggered quadrature amplitude modulator for providing an staggered quadrature amplitude modulated (SQAM) signal from a received signal; a data-aided carrier tracking loop (CTL) and a data-aided symbol timing recovery (STR) loop. The data-aided CTL operates such that the data-aided CTL is now insensitive to timing phase offset. | 11-11-2010 |
| 20100283911 | DECOUPLED DATA-AIDED SYMBOL TIMING RECOVERY LOOP - A receiver is an ATSC (Advanced Television Systems Committee)-receiver and comprises a staggered quadrature amplitude modulator for providing an staggered quadrature amplitude modulated (SQAM) signal from a received signal; a data-aided carrier tracking loop (CTL) and a data-aided symbol timing recovery (STR) loop. The data-aided STR loop operates such that the data-aided STR loop is now insensitive to carrier phase offset. | 11-11-2010 |
| 20100284494 | BLIND CARRIER TRACKING LOOP - A receiver is an ATSC (Advanced Television Systems Committee)-receiver and comprises a phase lock loop (PLL) for performing carrier tracking of a carrier in a received signal. The PLL includes a detector ( | 11-11-2010 |
| 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 |
