Abstract

The invention discloses a polarization code decoder. The polarization code decoder comprises a decoding unit and a control unit in communication connection with the decoding unit, wherein the decodingunit comprises m input ends and n paths, and the m input ends are selectively connected with the n paths; the control unit is used for sending a first control signal to the decoding unit, and the first control signal is used for indicating an SC decoding mode or an SCLw1 decoding mode; and the decoding unit is used for receiving the first control signal sent by the control unit and configuring anSC decoding mode for decoding or configuring an SCLw1 decoding mode for decoding according to the first control signal. Thus, according to the polarization code decoder provided by the invention, different decoding modes can be realized through selective connection of the input end and the path; therefore, decoding of different performances and different parallelism degrees can be realized through one decoder, flexible selection is realized in the aspect of speed performance, two-stage decoding can be realized based on the decoder, and the PDCCH blind detection process is accelerated.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a polar code decoder. Background technique [0002] In a communication system, channel coding can ensure against interference in information transmission and reliably transmit information data to receiving devices. Usually, the sending device needs to encode the information data to obtain coded bits, interleave the coded bits, map the interleaved bits into modulation symbols, and then process and send the modulation symbols through the communication channel. After the receiving device receives the modulation symbols, it decodes them through a decoder and recovers them into information data. [0003] 3GPP selects polar (Polar) codes for 5G enhanced mobile broadband (enhance mobile broadband, eMBB) service control channel coding. With its unique channel polarization characteristics, Polar codes can achieve better error correction performance than other known code types suc...
