Abstract: An LR-WPAN(Low Rate-Wireless Personal Area Network) constructing method adopting a favorable modulation system among heterogeneous modulation/demodulation systems is provided to compose network efficiently by using an efficient modulation method according to the application of network in low frequency band of LR-WPAN. A beacon frame is modulated by using one of heterogeneous modulation method in a beacon cycle. A coordinator transmits the beacon frame(506). A network connection request of a device is determined by waiting the transmission of the next beacon in the selected modulation method(510). If there is no connection request, the beacon frame modulated into the other modulation/demodulation system is transmitted(512). If there is a connection request, the coordinator responses the connection request and determines the selected modulation/demodulation method as a transmission/reception method(516).

A parallel synchronizing part(520) includes buffers receiving an output of the parallel part. A counter(530) outputs a counter value for estimating a delivery time of a UWB(Ultra Wide Band) signal based on a sampling data maintained in the parallel synchronizing part. A system clock generator(540) provides a reference clock. The parallel part has a demuxer(510), receives an operation clock from a multiplier(550) multiplying a clock of the system clock generator, and parallels the sampling data of a clock frequency of the system clock.

Abstract: A multi-mode transmission/reception apparatus in an LR-WPAN(Low Rate-Wireless Personal Area Network) and a transmitting/receiving method thereof are provided to configure a network using devices which support different sorts of modulation/demodulation schemes by performing a multi-mode modulation/demodulation. A multi-mode transmission/reception apparatus in an LR-WPAN includes a multi-mode modem unit(100), a frequency mixing and clock generating unit(200), and a multi-mode transmission/reception unit(300). The multi-mode modem unit modulates and demodulates a transmission/reception signal digitally by selectively performing a multi-mode low frequency modulation/demodulation in response to a predetermined control signal. The frequency mixing and clock generating unit generates a sampling frequency provided to the multi-mode low frequency modulation/demodulation in response to the control signal, and generates a carrier frequency. The multi-mode transmission/reception unit converts the digital signal generated from the multi-mode modem unit into an analog signal, and up-converts the converted analog signal into a wireless modulation signal corresponding to the transmission channel based on the carrier frequency. The multi-mode transmission/reception unit down-converts the wireless modulation signal received from an antenna into an intermediate frequency based on the carrier frequency, and converts the down-converted intermediate frequency signal into a digital intermediate frequency modulation signal.
