Wireless Personal Area Networks ZIGBEE RECEIVER AND RECEIVING METHOD THEREOF

The present invention relates to a wireless private network ZigBee receiver and a receiving method capable of ensuring the spreading gain by a reduction in data transfer rate (data rate), A wireless private network ZigBee receiver based wireless private network ZigBee receiver including a plurality of functional units consisting of a predetermined symbol, and to receive the signal packets repeated by each of the plurality of functional units is a predetermined number of expansions in accordance with the present invention, the pre- the succession a plurality of functional units each symbol of expansions set when a packet signal in correlation repeated a preamble based on the symbol and the extension number to obtain a plurality of preamble correlation values, accumulating the plurality of preamble correlation values, and the accumulated preamble when the correlation value by using the cumulative value detecting a preamble to input the preamble synchronization signal from the preamble detecting section and the preamble detection unit for generating a preamble synchronization signal, for scaling the number of the preset, the symbol of the extended number of SFD unit included in the signal packet in a row of each group is set based on SFD Compared to the bees, when matched by expansions and includes a SFD synchronization to generate a synchronization signal SFD. In addition, we propose such a wireless private network reception of ZigBee receiver method. Wireless, private network, WPAN, Zigbee, IEEE 802.15.4, synchronous, packet, extended
