Problems solved by technology

However, the dummy bits added in each channel of data have no practical meaning except to provide convenience for column interleaving, which requires a large amount of storage resources and increases the cost.

Embodiment Construction

[0050] In order to facilitate the understanding of the technical solution and technical features of the present invention, a principle introduction to the rate matching process in the prior art will be made below, and then the present invention will be described in detail in conjunction with the drawings and embodiments.

[0051] Referring to Fig. 1(a), this figure shows the rate matching process according to the requirements of the protocol 36212-880. The input of LTE system rate matching is three 8bits parallel inputs and one 8bits parallel output. Due to the different input methods of the three-way data, their position indexes are different:

[0052] The j-th line input data of the first and second channels (including the Dummy bits inserted by rate matching, Dummy bits are also called sub-units or filling bits, depending on the processing method, all Dummy bits can be filled with 0 or 1; Dummy Bits are usually filled in the head of the input data) After the column is exch...

Abstract

The embodiment of the invention provides a parallel rate matching method applied to a long term evolution (LTE) system. The method comprises the following steps of: computing the interleaving address of three paths of data comprising Dummy bits; removing the Dummy bits from the interleaving address, recalculating the interleaving address, and storing the data from which the Dummy bits are removed according to the recalculated interleaving address; acquiring a data reading starting address and a data reading ending address; reading the data from the starting address to the ending address, judging whether the total volume of read data reaches a preset total volume or not, and if the total volume of the read data does not reach the preset total volume, starting cyclically reading between the zero address of a memory space and the ending address until the total volume of the read data reaches the preset total volume; and performing bit reforming on the read data to obtain rate-matched data. The invention also provides a parallel rate matching device applied to the LTE system. By the technical scheme in the embodiment of the invention, rate matching is realized under the condition of no addition of the Dummy bits.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a parallel rate matching method and device applied to an LTE system. Background technique [0002] The LTE system is the same as the cellular mobile communication system, the multi-rate matching scheme is a key issue, and the rate matching is the core algorithm of the multi-rate scheme. The rate matching mechanism effectively meets the QoS requirements of different services, enabling services of different rates to be multiplexed together effectively. There are two rate matching methods in the prior art, one is DSP-based rate matching, and the other is FPGA-based rate matching. However, no matter what method is used to achieve rate matching, it is necessary to add dummy bits to each channel of data in accordance with the requirements of the protocol 36212-880, and then perform column interleaving on the added dummy data, and then store the interleaved data ...
