摘　　要：提出一种便携式的无线通信系统,它采用OMAP5912作为系统中央处理器,利用Wi-Fi模块组建Ad-Hoc无线网络,采用G729a编解码传输语音信息,并利用混音技术实现多方通话功能。测试表明,该系统不需要专用基站,可随时随地实现实时语音通信,适合应急通信等无线应用场合。A portable wireless communication system is proposed. It selects OMAP5912 as the system processer, sets up Ad-Hoc wire- less network using Wi-Fi modules. It realizes voice transfer with G729a coding/decoding algorithm, and supports multi-party call using Mix Audio Technique. Tests show that the system needs no special base station, supports real-time voice communication at any time and in any place. The system is suitable for portable wireless applications such as emergency communication.
