Abstract


Software radio on the same hardware platform , by loading different software can achieve different way communication . Software bus technology in software-defined radio , common communications platform can build a distributed communications environment , the basic programming interface for communications to upper software applications provide , the software engineer from the radio - oriented , trivial programming freed to focus on more complex and more convenient software application . Thus has good practical value and broad application prospects . In a distributed processing environment for software radio , the unique architecture of the system and the complexity of distributed communication needs , based on CORBA (Common Object Request Broker Architecture) provides distributed processing technology , in between the operating system and the upper application component of a software bus layer , using the software communications Architecture SCA (Software Communication Architecture) the core framework as a software bus architecture , the functionality of the software bus core framework is divided into : basic application interface framework control interface , as well as the framework of service interfaces three class , take this mask off the radio the details of the underlying hardware platform , provides the basic programming interface to the upper waveform applications . Design ideas and functionality of the software bus division , the core framework for the various types of interfaces defined IDL (Interface Definition Language) , provides for the various properties of the interface , operation, and should be implemented functionality , and using UML (Unified Modeling Language) diagram indicates the relationship between the interface . In addition , the article also select the most representative in the core framework domain manager interface , detailed discussion of the Design and Implementation . CORBA-based software bus technology in software radio applications , software developers to the upper bring a great convenience , but also introduces some problems , such as the introduction of CORBA additional delay . The solution to these problems has yet to be further improvement of CORBA .
