Embodiment Construction

[0109] Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the present invention is described in further detail:

[0110] Such as figure 1 Shown is a schematic structural diagram of an embodiment of the data processing device of the present invention.

[0111] The data processing device disclosed in the present invention includes a QPP (Quadratic Permutation Polynomial, quadratic permutation polynomial) interleaver and a component encoder.

[0112] 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 f 1 The absolute value of is odd, f 2 The absolute value of is an even number, and K represents the length of the input information sequence.

[0113] The above interleaver is with offset f 0 The ...

Abstract

The invention discloses a data processing device and a method; the data processing device comprises a QPP interleaver and a weight encoder; and after encoding an input information sequence, the weight encoder encodes the feedbacked bit, distributes the information bit and the parity bit, and outputs the bit. The technical scheme disclosed by the invention adopts only one weight encoder, and simultaneously, reduces the number of last bit, effectively reduces the delayed processing of encoding and rate matching by adopting a simpler and more high-efficiency encoding method and a CBRM rate matching method, simplifies the complicacy of encoding and rate matching, improves the processing speed of encoding and rate matching, and improves the encoding efficiency and the spectrum 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 ...
