Title:
LDPC CODING METHOD AND APPARATUS, LDPC DECODING METHOD AND APPARATUS, AND LDPC CODING/DECODING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/000373
Kind Code:
A1
Abstract:
The present application relates to an LDPC coding method and apparatus, an LDPC decoding method and apparatus, and an LDPC coding/decoding system. The LDPC coding method comprises the steps of: starting from an interception position determined by a Zc value, intercepting coded data to obtain intercepted data having a length which is a data length that can be sent after being coded; and transmitting the intercepted data to a receiving end, the intercepted data being used for instructing the receiving end to perform decoding processing on filled data using an LDPC decoding matrix determined by a coding/decoding parameter, and the filled data being obtained by performing blank bit filling on the intercepted data by the receiving end using a filling quantity determined by the Zc value. The present application performs simplification processing on a low-density parity-check code process in the 5G standard according to requirements of a digital communication system and characteristics of a microwave channel, thereby reducing the complexity of implementation while ensuring system performance and significantly reducing a resource occupation rate of a chip.
