Robust carrier identifying method and apparatus for bandwidth-on-demand (BOD) system |
摘要 |
An approach for identifying a particular carrier among a plurality of carriers in a satellite communication system is disclosed. A transmitter multiplies an encoded signal by a prescribed periodic sequence to form a watermarked signal and transmits the watermarked signal associated with a particular carrier over a communication channel. A receiver tunes to one of the carriers and extracts a data sequence from the one carrier. The receiver multiplies the data sequence with the prescribed periodic sequence to form another watermarked signal and determines whether the watermarked signals match.
