Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0024] figure 1 What is shown is a schematic diagram of an implementation environment provided according to an embodiment of the present application. Such as figure 1 As shown, the implementation environment 100 includes a baseband unit 110 and a radio frequency unit 120 . When the baseband unit 110 and the radio frequency unit 120 perform data transmission, at the data interface of the baseband unit 110 and the radio frequency unit 120, a data compression module is usually set to compress the ...

Abstract

The invention provides a data compression method and a data compression device. The data compression method comprises the steps that a first compression algorithm is selected as a compression algorithm corresponding to data to be compressed according to a first modulation mode corresponding to the data to be compressed and a first preset data bit width, and the first compression algorithm is a compression algorithm with the minimum error vector amplitude after pre-compression processing is carried out on the sample data in multiple compression algorithms under the first modulation mode and the first preset data bit width; and the to-be-compressed data are compressed according to the first compression algorithm. According to the embodiment of the invention, the compression algorithm corresponding to the compressed data can be selected for different compressed data, and the compression error can be reduced.

Description

technical field [0001] The present application relates to the technical field of data compression, in particular to a data compression method and a compression device thereof. Background technique [0002] In order to reduce the amount of data transmission between the baseband unit and the radio frequency unit, the data is usually compressed before being transmitted, and a fixed compression algorithm is usually used to compress the data to be compressed. However, since the compression algorithms applicable to different data to be compressed may be different, when the same compression algorithm is used to compress different data to be compressed, some of the data to be compressed will generate large compression errors after being compressed. Contents of the invention [0003] In view of this, the embodiments of the present application are dedicated to providing a data compression method and a compression device thereof, so as to solve the problem that some data to be compre...
