WIRELESS PERSONAL AREA NETWORKS ZIGBEE RECEIVER AND RECEIVING METHOD THEREOF

摘要

A wireless personal area network Zigbee receiver and a receiving method for improving receiving sensitivity are provided to secure spreading gain through reduction of data rate and maintain compatibility of Zigbee signal packet. A receiver(100) receives a signal packet from a wireless personal area network Zigbee transmitter(10). A preamble detecting part(200) accumulates correlation value as repeating symbols of the signal packet received from the receiver as the number of a preamble standard symbol. The preamble synchronization signal is generated by detecting the preamble by using accumulation correlation value.
