Abstract

The embodiment of the invention discloses a data compression and decompression method, system, and electronic equipment. The data compression method comprises the following steps: grouping to-be-compressed data based on a preset rule; solving an absolute of each to-be-compressed data in each group, and determining the maximum value in the absolute values in each group; computing the data compression measurement value of each group according to the absolute value in each group; determining a compression factor of each to-be-compressed data in the corresponding group based on the data compression balance value and the absolute value of each to-be-compressed data in the corresponding group; and compressing each to-be-compressed data in the corresponding group according to the compression factor of each to-be-compressed data in the corresponding group and the preset target compression absolution value bit width. By adopting the above technical scheme disclosed by the invention, the IQ datacan be effectively compressed, the compression loss of small signal is reduced, and the compression performance is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular to a data compression and decompression method, system and electronic equipment. Background technique [0002] In the mobile communication system, the TD-LTE base station is a distributed base station equipment, including BBU (Base BaMdUMit, base band unit) and RRU (Remote RF UMit, radio frequency remote unit), BBU and RRU are connected by optical fiber, bidirectional The IQ data is transmitted, and the IQ data is a baseband digital signal, including an I channel signal and a Q channel signal. [0003] With the development of mobile communication technology, high-speed and large-capacity data transmission is an inevitable trend. The increase in the amount of data also puts forward higher requirements on the optical fiber data transmission capability of the base station. At the same time, higher-speed optical modules are required, and the c...
