A signal method of processing in a receiver a signal that has been encoded and interleaved in a transmitter comprising: receiving a signal, process the signal to obtain a stream of soft metrics representing bit probability of symbols in a predetermined constellation; applying to said soft metric a compression operation that preserves the total length of each group of soft metrics relative to a same constellation symbol; rearranging the stream of compressed soft metrics so as to inverse the interleaving done in the transmitter.

A decoder including a compression module configured to select one or more nodes from a plurality of nodes associated with data being decoded by the decoder, where each node includes one or more bits, and to compress the one or more bits associated with the selected nodes. A memory is configured to store the compressed one or more bits associated with the selected nodes.

Embodiments of this application disclose a polar coding method, apparatus, and device, so as to reduce storage overheads of a system. A sequence for polar coding is obtained based on a length M of a target polar code, wherein the sequence comprises L sequence numbers, ordering of the L sequence numbers in the sequence is the same as ordering of the L sequence numbers in a maximum mother code sequence, wherein the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in ascending order or descending order of reliability metrics, wherein L and N are integer power of 2, M is smaller than or equal to L, L is smaller than or equal to N.

A radio data communication system includes a plurality of radio units, each radio unit having a transceiver and an antenna, and a gateway unit connected to each of the plurality of radio units via a first data bus. Each transceiver in the plurality of radio units is configured to receive a data signal from a respective antenna, compress the received data signal using a data compression algorithm, and transmit the compressed data signal to the gateway unit via the first data bus. The data compression algorithm includes a bit shifting operation performed by a multiply-accumulate operation.

The present disclosure relates to polar coding methods, apparatuses, and devices. In one example method, a sequence for polar coding is obtained based on a length M of a target polar code, where the sequence comprises L sequence numbers, an order of the L sequence numbers in the sequence is the same as an order of the L sequence numbers in a maximum mother code sequence, where the maximum mother code sequence is obtained by sorting N sequence numbers of N polarized channels in an ascending order or a descending order of reliability metrics, and where L and N are integer power of 2, M is smaller than or equal to L, and L is smaller than or equal to N.
