摘　　要：针对基于软件通信体系结构(SCA)的通信系统存在着实时性不高、冗余度较大、无法故障恢复等不足,将数据分发服务(DDS)技术引入到SCA架构中,形成了一种扩展方案。在完全保持SCA规范兼容的前提下,用DDS作为波形组件间的传输手段,有效地提高了基于SCA的通信系统的实时性,降低了系统的冗余度,实现了单个软件模块的动态重构。此方案已经在某仿真通信系统中得到了成功的应用。Communication system based on software communication architecture （SCA） has some deficiencies, such as real-time is not high, redundant and no fault recovery. The data distribution service （DDS） technology is introduced into SCA, form a kind of expansion solution. At the precondition of securing the SCA compatible, DDS is used as the transmission means between waveform components, the real-time performance of the communication is effectively improved, the system redundancy is reduced, self-refactoring of single software module is implemented. This solution is applied in XXX emulational communication system.
