Problems solved by technology
The design scheme of the prior art integrates the interface transmission part circuit and the baseband processing unit circuit on a single board, and the failure of the interface circuit will affect the reliability of the entire single board
[0015] 3. If the circuit design on the board is fixed, the transmission interface devices on the board (including optical interface and electrical interface) will have limitations in terms of speed, transmission distance, etc. For example, the speed cannot be doubled, and the speed cannot be increased. transmission of 10 kilometers, etc., therefore, this design will limit the configuration of the entire system

The invention discloses a baseband processing device for a wireless base station system, comprising: a baseband core processing module, an interface driver module and at least one transmission interface module, wherein the baseband core processing module and the interface driver module are located on the same motherboard; each transmission The interface module is located on a daughter board; the mother board and the daughter board are connected through connectors. The invention can realize the adaptation of the same baseband processing unit and different interface radio frequency processing units, improve the flexibility and expansibility of base station system configuration, and facilitate system maintenance.
Description
technical field [0001] The invention relates to the technical field of communication equipment, in particular to a baseband processing device for a wireless base station system. Background technique [0002] The base station in the mobile communication system is mainly responsible for various functions related to wireless, providing the UM interface (interface between the base station subsystem and the mobile station) for the MS (mobile station) to access the system, and directly connecting with the MS through wireless. A failure of a base station has a great impact on the entire mobile network. With the rapid development of the mobile communication industry, the number of base stations has increased sharply, and the distribution is intricate, which makes the commissioning and maintenance of the base station system more and more complicated. [0003] At present, in order to facilitate network coverage and engineering design, the baseband processing unit and the radio freque...
