| Abstract: | A portable wireless communication system is proposed.It selects OMAP5912 as the system processer,sets up Ad-Hoc wireless 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. |
