Abstract

The invention discloses a data sending and receiving method and device. The method includes: selecting a compression factor and a compression identifier according to the numerical value of the original data, the original data including a sign bit and a value bit; removing the unremoved part of the original data according to the preset compressed effective number of bits and the compression factor bits to obtain initial compressed data; compress the initial compressed data according to the effective number of bits to obtain compressed valid data; send the encapsulated sign bit, compressed valid data and compressed identifier. Using this method, the original data can be quickly compressed, the problem of excessive data transmission pressure caused by the large amount of transmitted data is solved, and the time for data compression is effectively reduced. It is simpler in implementation, occupies less resources and is simple and easy to transmit data.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of mobile communication, and in particular, to a data sending and receiving method and device. Background technique [0002] With the rapid development of mobile communication technology, high-speed and large-capacity data transmission has become an inevitable trend. The increase in the amount of transmitted data puts forward higher requirements for the optical fiber data transmission of the base station. For example, with the increase of Long Term Evolution (LTE) bandwidth or the number of antennas, the transmission data of the optical port continues to increase. When a single optical fiber cannot meet the transmission rate, it can only be achieved by increasing the optical fiber rate or increasing the number of optical fibers. High-speed data transmission, both of which will increase equipment costs. [0003] The increase in the amount of data transmission has greatly caused the...
