Design And Implementation Of Wideband Communication Signal Analysis Core Software Based On AP-SoC

Broadband communication signal analyzer is an important tool to observe,detect and analyse the broadband communication signal in multi domain and panoramic range,which plays a very important role in the development,production,installation and maintenance of the electronic communication equipment.Broadband communication signal analysis software,as an indispensable part of broadband communication signal analyzer,has very important research significance and research value.Based on AP-SoC platform,the core software of the broadband communication signal analyzer is researched and designed in a new approach,finally,the observation and analysis of broadband communication signals in multi domain is realized based on the AP-SoC handheld platform.In this paper,firstly,the the overall scheme of the whole system is briefly introduced from two aspects of hardware and software,in addition,a detailed needs analysis is carried out for the system software and application software of core software to the broadband communication signal analyzer based on AP-SoC,and modeling on the application software with UML modeling language from two static and dynamic aspects using the case diagram and the sequence diagram.Then,according to the requirement analysis and software modeling,the system software and application software of the core software are implemented in detail.The system level software includes Boot Load transplantation,Linux kernel depth cutting and transplantation,and the design of the related interface and IP core drivers,the application software includes the design and implementation of the baseband data interface layer,system initialization module,system self-test module,thread management module,baseband signal data acquisition module,signal spectrum analysis module,signal vector analysis module,data frame module and network layer.For the application software,in order to improve development efficiency,it is basically modular,and when designed,the idea of hierarchical modularization is adopted.Finally,after the completion of the coding,the core software of broadband communication signal analyzer is tested in the aspect of functionality and performance to verify whether the core software meets the initial requirements.The relevant test shows that the core software of the broadband communication signal analyzer based on AP-SoC can completely receive broadband communication signals commonly,be able to finsh the spectrum analysis and the vector analysis rightly,and can sent analysis result to the remote interface display software correctly.This paper meets the basic requirements of the requirement analysis early proposed.
