Embodiment Construction

[0086] The main idea of ​​the present invention is that in the existing rate matching technology, the interleaving address generation method of the system bit data stream and the check 1 data stream is the same, as shown in formula 1, and the interleaving address generation formula of the check 2 data stream is as follows Formula 2 shows:

[0087] Formula 1)

[0088] Formula (2)

[0089] Comparing these two interleaving formulas, it can be seen that formula (2) is shifted to the right by one position in the input data matrix than formula (1), therefore, the present invention considers that the input data of verification 2 data flow is shifted to the left by one position (to be corrected) In this way, the interleaving address generation method of the verification 2 data stream is exactly the same as the interleaving address generation method of the system bit data stream and the verification 1 data stream, so that One interleaving address generation device can b...

Abstract

The invention discloses a serial processing method and a serial processing device for rate matching and relates to the channel coding technology in a mobile communication system. the method includes the steps that system bit data stream, check I data stream and check II data stream are received, and the system bit data stream is interwoven and then is cached in a first cache region of a storage; the corresponding data in the check I data stream and the check II data stream are interwoven simultaneously, and then is cached in a second cache region of the storage; and valid data in the storage is read so as to realize the rate matching. Compared with the existing rate matching device, the technical scheme of the invention simplifies a storage structure, reduces the complexity of a system and improves the processing efficiency of the rate matching.

Description

technical field [0001] The invention relates to a channel coding part in a mobile communication system, in particular to a rate matching serial processing method and device. Background technique [0002] In a mobile communication system, part of the redundant data is generated after the data transmitted in the channel is channel coded. These redundant information are used to provide more decoding information for the decoder and improve the success rate of decoding. However, if all the redundant information is transmission, resulting in a decrease in transmission efficiency. Therefore, a better method is to select the amount of information to be transmitted according to the quality of the channel. For example, when the channel quality is relatively good, only the original information is transmitted; otherwise, more parity bits are transmitted in addition to the original information bits. Therefore, it is necessary to selectively transmit the data generated by the channel enc...
