摘要： 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.

摘要： An apparatus comprises an adaptive filter having groups of taps, each group comprising at least one tap having an associated tap value; and a controller for selecting a scaling factor for at least one group of taps as a function of tap values of the group. The controller further adjusts an error value as a function of the selected scaling factor. The adaptive filter adapts tap values of the at least one group of taps as a function of the adjusted error value.

摘要： A system for receiving a composite signal including a main component and a multipath component includes a demodulator chain having adaptive circuitry controllable in response to a control signal to compensate for the multipath component. In this system, a control signal generator includes a phase error estimator, which generates a signal representing an estimate of the phase error between the received main component and the received multipath component. A controller generates the control signal in responsive to the phase error signal.

摘要： The determination of the signal modulation format for a channel is an important aspect of the operation of a signal receiver. A method (700) is described including the steps of receiving (710) a signal, comparing (720) a sample of the received signal to a first threshold value and a second threshold value, creating (720) a signal profile based on the comparison, and selecting (750) a modulation format for the received signal based on the signal profile. An apparatus (500) is also described including a ring counter (510) that receives a sample of an input signal, compares the sample to a first threshold value and a second threshold value, and creates a signal profile for the input signal, a signal profiler (550) that compares the signal profile for the input signal to at least two reference profiles, and a detector (560) that determines a modulation format for the input signal based on the comparison in the signal profiler (550).

摘要： A software packet error system for a High Definition Television (HDTV) receiver. A data packet error signal is transferred from a forward error correcting Reed-Solomon decoder to a transport processor. In response to a segment sync signal, the transport processor generates an error signal which appears on a programmable output pin. The software packet error signal is synchronized with the outgoing data packet signal such that each data packet is bracketed or framed by its associating packet error signal. Precession of the start of the data packets forwarded on the transport but relative to the start of the data packets appearing at the output of the decoder occurs as a result of a training packet generated for every 312 data packets. The precession is reset at the beginning of every field and is predictable across the field duration with sufficient accuracy to make the software packet error mechanism feasible.
