摘要： 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.

摘要： An apparatus and method for encoding a signal are provided. The apparatus and method of the present disclosure identify (404) the various portions, or bytes, of an incoming packet in a Reed-Solomon (RS) encoded packet as either data bytes, RS parity bytes, or trellis reset synchronization bytes. The data bytes are passed through without change. The trellis reset bytes are provided to a trellis encoder to determine new byte reset values (406). These new values are then stored (408) and later retrieved (410) when needed and used to modify the appropriate incoming parity bytes. The new incoming parity bytes are computed (412) using the new trellis reset byte values multiplied by, or added to, a weighting value retrieved from a table stored in memory based on a location of the parity byte and a location of the trellis reset byte in the RS encoded packet.
