Problems solved by technology

[0006] According to the existing processing flow, de-rate matching can only process 1 soft bit of data in one clock cycle. When the code rate is relatively low, de-rate matching becomes the bottleneck of system delay.

Abstract

The invention discloses a rate de-matching method comprising the following steps: distributing input data stream; outputting the data streams in multiple paths after being distributed in parallel; and processing the data streams output in multiple paths in parallel in dummy restoration and subblock de-interlacing modes. The invention also discloses a rate de-matching device. The method and the device of the invention can be used for increasing the rate de-matching processing speed.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a rate matching method and device. Background technique [0002] In the LTE (Long Term Evolution, long-term technological evolution) protocol, there are detailed technical solutions for the baseband processing at the sending side, such as the realization of Turbo coding, the realization of rate matching at the sending side, and so on. On the receiving side, the LTE protocol does not have a clear technical solution for baseband processing. For the baseband processing on the receiving side, one of the key points of implementation is to speed up the baseband processing on the receiving side, reduce the system delay, and reduce the complexity of the system. The processing speed of solution rate matching is to realize the simple and fast processing of the receiving side a key to [0003] De-rate matching is the inverse process of rate matching. The input data stream of...
