Problems solved by technology

Therefore, a large amount of data needs to be transmitted between the RRU and the BBU, so that a transmission line must be added between the RRU and the BBU, resulting in a significant increase in the complexity and cost of the system implementation

Abstract

The invention discloses a multi-antenna data compression method and equipment. The method comprises the following steps: calculating an antenna cross correlation coefficient, establishing an antenna mapping list according to the antenna cross correlation coefficient, selecting a reference antenna and a mapping antenna from the antenna mapping list, acquiring difference bits between the mapping antenna and the reference antenna, determining the number of the difference bits, keeping a sign bit, and intercepting other bits in the difference bits to a data compression bit length according to a Bit mapping identifier to obtain mapped mapping antenna data; and compressing the antenna cross correlation coefficient, reference antenna data and the mapped mapping antenna data. Through adoption of the multi-antenna data compression method and equipment, the data volume transmitted between a BBU (Base Band Unit) and an RRU (Remote Radio Unit) is reduced, and the demand of multi-antenna system deployment for a transmission link is lowered.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a multi-antenna data compression method and device. Background technique [0002] One of the salient features of the LTE system is the use of MIMO technology to improve system throughput. At the same time, macrocell base stations generally adopt a distributed architecture composed of a baseband unit BBU and a remote radio unit RRU. Under this architecture condition, the BBU and RRU The amount of data transmission between the antennas is proportional to the increase in the number of multi-antennas. In the current BBU and RRU system, the data processing flow of RRU is as follows: [0003] For the uplink signal, the radio frequency signal received by the antenna passes through the duplexer in the RRU, the low noise amplifier unit, and the radio frequency unit is down-converted into an intermediate frequency analog signal, and then converted into a digital signal by the analog-to...
