摘　　要：针对电台通信的实际情况,利用UDP协议、IP多点广播技术,提出了一种在局域网内基于多线程语音通信实现电台模拟仿真通信的方法,设计了模拟仿真电台通信的总体架构和实现方案,详细分析了多线程语音通信中所采用的Waveform Audio API采集播放音频、TrueSpeech音频压缩和多线程同步等关键技术,较好地实现了电台单频半双工和双频全双工两种工作模式的模拟仿真。According to actual situation of the communication stations, the thesis focuses on a project of Simulated Transmitter-receiver System based on the multithread voice communications. The project achieves the goal of Simulated Transmitter-receiver using UDP protocol and IP Multicast technology. The thesis stresses on the overall design and construction of the project, analyzes the key point in the design of multithread voice communication, including the recording and playback of audio by using Waveform Audio API, TrueSpeech speech codec algorithm, multithread synchronization and so on. It satisfactorily realizes the simulation of Shortwave Transmitter-receiver＇s Monochromatic Semiduplex and Dual-Band Full- Duplex working mode.
