Embodiment Construction

[0139] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0140] Such as figure 1 Shown is a schematic structural diagram of an embodiment of the data processing device of the present invention.

[0141] The data processing device disclosed in the present invention includes a QPP (Quadratic Permutation Polynomial, quadratic permutation polynomial) interleaver and a component encoder.

[0142] Among them, the QPP interleaver uses the interleaving function ∏(i)=(f 0 +f 1 ·i+f 2 i 2 )mod(K) will input information sequence A={a 0 , a 1 ,...,a K-1} for interleaving to obtain the interleaved sequence A ∏ ={a ∏(0) , a ∏(1) ,...,a ∏(K-1)}, where f 0 , f 1 , f 2 is an integer, and K represents the length of the input information sequence.

[0143] The above interleaver is with offset f 0 The QPP interleaver. f 0 Can be odd, for example f 0 = 1, f 0 The absolute value of ca...

Abstract

The invention discloses a data processing method and a method; the data processing device comprises a QPP interleaver and a component encoder, the component encoder encodes the input information sequence, the bits sent back from the component encoder are encoded and distributed to the last information bit and check bit which are outputted. The technical scheme includes that only a component encoder is adopted, and the number of tail bits is reduced at the same time, more simple and efficient encoding method and CBRM speed matching method are adopted to effectively reduce the encoding and processing delay of speed matching, simplify the complexity of encoding and speed matching and improve the processing speed of encoding and speed matching so that the encoding efficiency and frequency spectrum efficiency are improved.

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 ...
