摘要： A communication system comprises a packet stream transforming unit, a mapping unit and a transmission unit. The packet stream transforming unit is configured to receive a 4-bit packet stream and transform the 4-bit packet stream into a 6-bit packet stream. The mapping unit is configured to map the 6-bit packet stream into multiple ternary bit streams, and the mapping unit maps at least one idle symbol into the ternary bit streams according to at least one particular bit of the at least one idle symbol of the 6-bit packet stream. The transmission unit is configured to transmit the ternary bit streams to a remote communication device through a cable.

摘要： The present invention discloses an energy efficient network communication device comprising: a media-access-controller for outputting a transmission-end low power idle (LPI) indication and receiving a reception-end LPI indication; a media-independent-interface for generating a transmission-end LPI signal according to the transmission-end LPI indication, and generating the reception-end LPI indication according to a reception-end LPI signal; and a physical-layer-circuit, coupled to several pairs of transmission lines, for converting the transmission-end LPI signal into a transmission signal to send it to a reception end for requesting an LPI mode and receiving a reception signal from the reception end to convert it into the reception-end LPI signal. Said physical-layer-circuit uses some of the several pairs of transmission lines for transmission and reception when keeping the other pairs of transmission lines unused to save power; furthermore, the physical-layer-circuit can enter the LPI mode from an idle mode for additional power saving.

摘要： A detector circuit includes a calculator circuit and a comparator circuit. The calculator circuit is configured to generate a plurality of first calculation values according to a plurality of first calculation symbols of a Pseudo-Noise Sequence and a plurality of second calculation symbols of a received signal, and generate a second calculation value according to the first calculation values. If a sign of a symbol of the Pseudo-Noise Sequence is the same to a sign of an adjacent symbol, the symbol is one of the first calculation symbols, and the second calculation symbols are corresponding to the first calculation symbols respectively. The comparator circuit is configured to generate a comparison result according to the second calculation value and a threshold value. The comparison result is configured for determining whether the detector circuit correctly receives the Pseudo-Noise Sequence.
