Patent Searching and Data


Title:
PUNCTURING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/206055
Kind Code:
A1
Abstract:
Disclosed in the present invention are a puncturing method and device. The method comprises: acquiring a frozen index set of polar codes with the length of N symbols and an N*N generation matrix; transforming, according to the frozen set, N row vectors of the N*N generation matrix to obtain an N*N transformation matrix; determining, according to N column vectors of the N*N transformation matrix, the N weights corresponding to the N column vectors; puncturing, according to the N weights, the polar codes with the length of N symbols to obtain transmittable transmission symbols with the length of M, where N and M are integers greater than or equal to 1, and N is greater than M. The present invention can reduce the frame error rate of transmission data.
