Abstract

The invention provides a signaling coding method and a signaling coding system based on BCH code and short LDPC code cascading. The method comprises the following steps: establishing a zero padding group table of the correspondence between the sequences of zero padding groups divided in turn and the positions of the zero padding groups based on a default LDPC code check matrix and establishing a punching group table of the correspondence between the sequences of punching groups divided in turn and the positions of the punching groups based on the default LDPC code check matrix; zero-padding an input signaling after scrambling treatment according to the zero padding group; sequentially calculating the BCH code check bit and the LPDC code check bit corresponding to the signaling after zero padding based on preset BCH code and LPDC code error correction coding parameters; and determining the number of punching bits of the LPDC code check bit based on the preset linear relationship between the code length of the signaling and the number of punching bits, and punching the LDPC code check bit according to the number and according to the punching group table.

Description

technical field [0001] The present invention relates to a signaling encoding method and system, in particular to a signaling encoding method and system based on concatenated BCH codes and short LDPC codes. Background technique [0002] With the rapid development of world economy and culture, users' demand for wireless data services increases rapidly. Relying solely on the traditional wireless broadcast network or the traditional wireless two-way communication network, it is impossible to realize the optimal transmission of data services. At the same time, people are no longer satisfied with watching traditional wireless broadcast TV services, and the demand for new wireless broadcast TV services is becoming stronger and stronger. The Next Generation Broadcasting Network Wireless (NGB-W) system can realize the fusion and coexistence of wireless broadcasting and wireless two-way communication. A necessary way to support wired and wireless converged innovative services. [0...
