Abstract

The invention discloses a data processing device and a method thereof. The data processing device comprises an interleaver and a component encoder. The method comprises: performing first continuous encoding of an input information sequence and an interleaved input information sequence through the component encoder, calculating a loop state value based on the results of the first step, initializing the register of the component encoder with the calculated value, performing second continuous encoding of the input information sequence and the interleaved input information sequence through the component encoder, and outputting the results of the second continuous encoding as final encoding results. In the technical scheme disclosed by the invention, only one component encoder is used, the quantity of tail bits is reduced simultaneously, and the simpler and more efficient encoding method and the CBRM rate matching method are adopted, thereby effectively reducing processing delay of matching coding with rate, simplifying the complexity of encoding and rate matching, improving the processing speed of encoding and rate matching, and enhancing the encoding efficiency and the spectral efficiency.

Description

technical field [0001] The present invention relates to the field of digital communication, in particular, the present invention relates to a data processing device and method thereof. Background technique [0002] During the transmission process of digital signals, errors will occur due to the influence of noise and interference. In the communication system, error correction coding technology is generally used to ensure reliable transmission. Turbo code is a coding scheme proposed by C.Berrou et al. in 1993. Because it has better performance than other codes in the application environment of low signal-to-noise ratio, Turbo code is used as a wireless channel in various mobile communication systems. One of the coding standards. Generally, a Turbo encoder consists of two systematic recursive convolutional (RSC) encoders, an interleaver and a deleter. [0003] With the continuous development of mobile communication, Turbo coding and decoding technology has been continuously ...
