Title:
INTERLEAVING PROCESSING METHOD AND DEVICE FOR POLAR CODES
Document Type and Number:
WIPO Patent Application WO/2018/228592
Kind Code:
A1
Abstract:
An interleaving processing method and device for polar codes. The method comprises: determining N bits to be encoded, where N is a positive integer (S210); acquiring a first sequence of serial numbers of N polarization channels, wherein the first sequence indicates reliability rankings of the N polarization channels (S220); performing polar encoding on the N bits to be encoded to obtain encoded bits (S230); and performing interleaving processing on the encoded bits according to the first sequence (S240). Since the first sequence indicating the reliability rankings of the polarization channels is a sequence already existing in a polar code encoding process, the above interleaving processing does not require an additional storage resource for storing the first sequence, reducing usage of storage resources. Furthermore, interleaving processing is performed on the encoded bits according to the existing first sequence and so can be easily accomplished.
