发明名称 End of communication detection
摘要 An apparatus for detecting the end of a communication is disclosed. The apparatus includes an interface circuit for receiving an encoded signal and a carrier signal recovery circuit coupled to an output of the interface circuit. The carrier signal recovery circuit is configured to output a carrier signal of the encoded signal and a second signal that is out of phase with the carrier signal. The apparatus also includes a decoding circuit configured to decode the encoded signal as a function of both the encoded signal and the carrier signal output by the carrier signal recovery circuit. The apparatus also includes a detection circuit configured to detect an indication of an end of a communication in the encoded signal as a function of both the encoded signal and the second signal.

主权项 1. An apparatus, comprising: an interface circuit for receiving an encoded signal; a carrier signal recovery circuit coupled to an output of the interface circuit and configured and arranged to determine and output a carrier signal of the encoded signal, andgenerate and output a second signal that is out of phase with the carrier signal; a decoding circuit, coupled to the output of the interface circuit and to the carrier signal recovery circuit, configured and arranged to decode the encoded signal as a function of the encoded signal and the carrier signal output by the carrier signal recovery circuit; and a detection circuit, coupled to the output of the interface circuit and to the carrier signal recovery circuit, configured and arranged to detect an indication of an end of a communication in the encoded signal as a function of the encoded signal and the second signal.
