摘要： A satellite television ground system, particularly for a make break satellite television signal system, includes an outdoor unit and an indoor unit that are in communication with each other via a single coaxial cable and an optional separate single conductor for power. The satellite television ground system is operative to measure and reverse frequency conversion errors utilizing DSP techniques, allowing for more precise generation and transmission of uplink signals from the satellite television ground system. Control data for the system is sent via a low data rate connection on a power cable thereof, or by a narrowband signaling channel via a coax cable. The system also utilizes a single reference oscillator to drive the various frequency synthesizers and the like. The satellite television ground system utilizes related oscillators for the uplink and downlink sections. Carrier frequency offset in the downlink is measured in a carrier tracking loop part of a television signal demodulator. The carrier frequency offset of the downlink is utilized to synthesize various frequency signals for the uplink and downlink sections to correct frequency errors. For the uplink section, the carrier frequency offset of the downlink is reversed in the uplink. If the uplink is on a different frequency, the measured offset of the system master oscillator can be scaled by different synthesizer ratios.

摘要： In a digital broadcast communications system, a higher priority component (11) and a lower priority component (10) are broadcast from a transmitter to a receiver. Each of these components generates a main (13, 30) and a supplemental (12, 20) signal, and each supplemental signal (12, 20) is advanced in time with respect to the corresponding main signal (13, 30). The main and supplemental signals for both the higher (11) and lower (10) priority components are combined (40) into a single signal, which is broadcast to a receiver. In the receiver, the time advanced supplemental signals are stored in a buffer (136, 150) to time align them with their corresponding main signals. Both main signals (133, 132) are processed in the normal manner in the receiver, and are also monitored (121) to detect a fading event. When a fading event is detected, the corresponding buffered supplemental signals are substituted for the faded main signals and normal processing continues.

摘要： A method and apparatus for identifying valid multipath energy peaks are described including locating an energy peak in a profile of energy peaks, categorizing the located energy peak based on a plurality of thresholds and processing energy peaks in at least one of the categories of located energy peaks. The method and apparatus further includes removing a direct current value component from each value in the profile of energy peaks, calculating a noise floor for a multipath searching window and determining a first threshold and a second threshold. The step and means for categorizing further includes determining if the located energy peak exceeds the first threshold, labeling the located energy peak as a false alarm, if the located energy peak does not exceed the first threshold, determining if the located energy peak exceeds the second threshold and labeling the located energy peak as confident, if the located energy peak exceeds the second threshold.

摘要： A method and apparatus for improving the reception of digitally modulated signals. A main signal (31) and a supplemental signal (21) are provided in the transmitter. The signals may be substantially identical except that the supplemental signal is advanced in time with respect to the main signal. The main and supplemental signals are sent from the transmitter to the receiver modulated on a signal. At the received, the supplemental signal is stored in a buffer. If the main signal is undesirably changed during transmission, corresponding portions of the supplement signal are substituted for the undesired portions of the main signal.
