摘要： A polar code construction method and an apparatus. A communication apparatus obtains a reliability weight sequence, and determines a first threshold that indicates a weight of lowest reliability of a subchannel corresponding to an information bit. The communication apparatus determines a non-pre-frozen subchannel corresponding to a content value greater than or equal to the first threshold in the reliability weight sequence as the subchannel corresponding to the information bit based on the first threshold, and performs polar coding on the information bit based on the subchannel corresponding to the information bit.

摘要： A method of encoding input data as a polar code includes generating unfrozen bits by adding at least one designated information bit to information bits which have been generated based on the input data, reordering the unfrozen bits and frozen bits by assigning the unfrozen bits to polarized sub-channels having higher reliability than the frozen bits having a value known to both of an encoder and a decoder, and generating a code word by polar-coding results of the reordering may be provided. The at least one designated information bit may have the value known to both the encoder and the decoder.

摘要： Methods and systems for providing a virtual HDBaseT® link. In one embodiment, a first switch transmits packets over an Ethernet network that includes one or more hops. The payload of each of the packets includes an HDBaseT® T-packet belonging to an HDBaseT® session. A first processor sets, for each packet from among a plurality of the packets, a timestamp value in the packet to correspond to the time at which the packet is transmitted by the first switch. A second switch receives the packets over the Ethernet network. A second processor calculates a clock correction value based on the timestamps in the plurality of packets, and utilizes the clock correction value to perform at least one of the following: (i) control transmission, by the second switch, of data in T-packets in the payloads of the packets, and (ii) recover a source clock of native media delivered over the Ethernet network.

摘要： An error correction code (ECC) decoder includes a finite state machine (FSM) controller and a shared logic circuit. The FSM controller generates a first control signal and a second control signal each corresponding to a certain state. The shared logic circuit includes a plurality of shared Galois field (GF) multipliers, a plurality of shared XOR arithmetic elements, and a plurality of shared multiplexers (MUXs), which are used for an operation selected between a syndrome operation, an error location polynomial operation, an error location operation and an error correction operation, in response to the first and second control signals.
