System and method for processing multi-core parallel assembly line signals of 4G broadband communication system

Abstract

The invention discloses a system and method for processing multi-core parallel assembly line signals of a 4G broadband communication system based on a GPP. In order to meet the strict requirement for the real-time performance of the 4G communication system, the cloud computing idea is utilized, the GPP serves as a computing resource, communication data are processed by utilizing an assembly line processing mode based on the GPP, and a large volume of data and computing tasks are divided into reasonable granularities through a scheduler and are distributed to assembly lines of all levels to be processed respectively. Under the condition that hardware performance is limited, the assembly line mode can meet the requirement for the real-time performance more easily, meanwhile, the time affluence amount is led in, and large delay variation can be borne by the system. Computing resources are fully utilized through reasonable dispatching. According to the system and method for processing the 4G broadband communication system multi-core parallel assembly line signals, three kinds of assembly lines are designed totally, one assembly line is suitable for processing a large data volume and higher in reliability, another assembly line is suitable for processing a small data volume and high in speed and flexibility, and the third assembly line is a composite assembly line based on twp application scenes and with a high degree of parallelism, wherein the performance of the third assembly line is obviously improved.

Description

technical field [0001] The present invention relates to a 4G broadband communication system technology, more precisely, to a GPP-based 4G broadband communication system multi-core parallel pipeline signal processing system and method, belonging to the technical field of wireless communication. Background technique [0002] 4G communication system is the abbreviation of the fourth generation mobile communication and its technology. Taking the Long Term Evolution (LTE) system as an example, the LTE system can realize data download and upload at speeds of 100 Mbps and 50 Mbps respectively, and can meet almost all users' needs for wireless services. 4G LTE Advanced uses carrier aggregation technology, and the peak downlink speed can reach 150Mbps. In addition, 4G can also be deployed in places where DSL (Digital Subscriber Line) and cable TV modems are not covered, and then extended to the entire area, which can effectively improve the performance of cell edge users, increase c...
