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.
