Abstract: This paper presents a new baseband-processor for Wireless Sensor Network(WSN) node based on ZigBee protocol. A dedicated demodulation architecture based on a non-coherent receiver algorithm is proposed to enhance the receive sensitivity and reduce the circuit redundancy. A new transceiver control unit is designed to manage the whole transmit and receive process. Other techniques, such as operation mode switch, power management, software platform optimization etc. are also implemented to reduce the power consumption as well as chip area. The design is implemented and verified in Altera Stratix S80 FPGA platform. Test results prove its expected functionality and its low power consumption.

Key words: ZigBee protocol, Wireless Sensor Network(WSN), baseband-processor
