| Abstract: | Aiming at the application of wireless sensor network in voice communication, this paper proposed a WSN-based voice communication system. Based on analysis of architecture and working principle of WSN, a node which adopted embedded processor MPC2194 as MCU, RF chip CC1000, codec CMX649 and storage core、power circuit as peripheral equipments was introduced. The design of system structure, hardware, software and protocols was discussed in detail. The system parameters were optimized through experiments, so as to achieve high-quality speech communication. |
