Problems solved by technology

The inserted padding bits are either fixed to 0, or 0 or 1 random bits, which have nothing to do with the transmission block bits that actually need to be transmitted, resulting in waste of resources and reducing the spectral efficiency of the system

Abstract

The invention discloses an encoding method of a 3G mobile communication system and a sending and receiving method thereof, and the encoding method is used for encoding the 3G mobile communication system and encoding filling bits of a code block segmentation treatment unit during the multiplexing process. The technical scheme is as follows: encoding the 3G mobile communication system, encoding the filling bits of the code block segmentation treatment unit during the multiplexing process, and taking information which is associated with input bits of a plurality of transmission blocks as the filling bits.

Description

technical field [0001] The present invention relates to a coding processing method for improving transmission performance in a third-generation mobile communication system (referred to as "3G mobile communication system"), in particular to a method for adding code block segmentation and wireless frame size equalization processing in the channel coding process A coding processing method for improving transmission performance with stuffing bits. Background technique [0002] With the process of global economic integration and social informatization, mobile communication services and mobile communication users are showing a trend of rapid growth. In order to meet the needs of personalization, intelligence and multimedia in mobile communication, the third generation mobile communication system is proposed. The existing 3G system standards mainly include WCDMA, TD-SCDMA and CDMA2000. The first two standards are mainly promoted by 3GPP organizations, while the latter is promoted b...
