Problems solved by technology

Especially after adopting 64-antenna or 128-antenna MIMO (Multiple-Input-Multiple-Output) RF front-end, the data from RF to baseband will increase significantly, so that the transmission bandwidth of FPGA needs to be greatly improved to solve the problem. If 12.5Gbps or 25Gbps FPGA, base station system design cost will increase significantly

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a physical connection device. Background technique [0002] The statements herein merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Current wireless communication products mainly use FPGA (field programmable logic gate array) to realize eCPRI (enhanced common public radio interface, CPRI is generally used in traditional communication systems, and eCPRI is generally used in 5G wireless communication technology) protocol for data interaction. In the VPX system, the RapidIO switching chip is used alone to realize data interaction. [0004] In the current base station design, the baseband part and the radio frequency part generally adopt remote technology, and the transmission protocol generally adopts eCPRI. Considering the transmission distance, generally do not directly use the eCPRI trans...
