Embodiment Construction

[0042] The device and method for parallel processing of an LTE Turbo encoder will be described below with reference to the accompanying drawings.

[0043] At first, the computing method of the method for multi-path parallel processing of the LTE Turbo encoder of the present invention is as follows:

[0044] The schematic diagram of a single-bit RSC encoder is shown in figure 2 shown.

[0045] In order to achieve multi-channel parallel processing, we assume M parallel input bits: c 1 ~ c M , let them pass through the RSC encoder in turn, and we will start deriving the encoded output bit z 1 ~z M and the corresponding shift register value.

[0046] c 1 After entering the RSC encoder by figure 2 The following relational expressions can be obtained:

[0047] z 1 = c 1 ⊕ D 3 ⊕ D 2 ⊕ D 1 ...

Abstract

The invention provides a data parallel encoded processing device in order to realize the parallel processing of LTE (Long Term Evolution) Turebo encoding. The device comprises a first parallel encoder, an inner interweaver and a second parallel encoder, wherein the first parallel encoder is used for carrying out parallel encoded processing on M bits of input data input from a first path; the inner interweaver is used for carrying out interwoven processing on M bits of data input from a second path parallel to the first path; and the second parallel encoder is used for receiving data subjected to the interwoven processing and carrying out parallel encoded processing on the data subjected to the interwoven processing, wherein M is equal to 2m, m is an integer being larger than 0 and smaller than 13, and the total bits of the input data can be divided by M with no remainder. In addition, the invention also provides a method for carrying out encoded processing on the data in order to realize the parallel processing of the LTE Turebo encoding.

Description

technical field [0001] The present invention relates to the field of encoding, more specifically, to a device and method for multi-channel parallel processing of a 3GPP LTE Turbo encoder. Background technique [0002] Turbo was born in 1993. It was first proposed by Berrou et al. in France on the basis of convolutional codes and concatenated codes. It is a new type of channel coding scheme with milestone significance, which brings the coding technology into the Shannon limit in a real sense. field of. [0003] Turbo codes use convolutional codes as component codes. Parallel concatenated convolutional codes (PCCC) are usually used between two component codes. An interleaver is introduced between component codes to reduce the correlation between component code encoders. sex, mimicking the form of random coding Shannon wanted. [0004] Section 5.1.3.2 of the 3GPP physical layer protocol TS36.212v8.6.0 stipulates the serial processing structure of the 3GPP LTE Turbo encoder, s...
