Problems solved by technology

[0005] For the case where the rate of the original sampling data does not match the data required by the processing module, the prior art sets a rate matching module to perform rate matching on the original sampling data, so that the rate of the output data of the rate matching module meets the requirements of the processing module for the data rate , but because it does not consider the data processing process of the processing module, the data output by the rate matching module can only meet the data rate requirements of the processing module, and cannot guarantee the validity and integrity of the output data

Abstract

A time domain processing device, a mobile communication terminal and a data processing method are provided. The device is used in the mobile communication terminal including an antenna and a data processing module and includes a sampling module connected with the antenna and a first rate matching module cascaded with a second rate matching module,wherein the first rate matching module is connected to the sampling module and the data processing module, the second rate matching module is connected to the data processing module, the first rate matching module includes a write unit, a first storage unit, a read unit and a control unit which controls the read unit to read the data from the first storage unit only if the gap between a read pointer and a write pointer of the first storage unit is larger than a first preset value. The device and method ensure the integrity and validity of the data which is output after a data rate converting process.

Description

technical field [0001] The invention relates to the field of third-generation mobile communication, in particular to a time-domain processing device, a mobile communication terminal and a data processing method. Background technique [0002] Channel equalization in the field of wireless communication has always been a research hotspot, and it is also a difficult point. [0003] In the prior art, in many cases, due to the mismatch between the original data and the input data of the processing module, for example, when performing channel equalization processing, the data rate sampled from the antenna is often lower than that of performing channel equalization operation processing. Therefore, before the data is input to the channel equalization processing module, it is necessary to perform rate matching processing (that is, rate conversion) on the sampled data to ensure that the channel equalization module can operate normally and obtain correct results. [0004] But at least ...
