Abstract: An apparatus for transmitting and receiving a high frequency in a wireless communication system amplifies a signal received by a transceiving antenna using a low-noise amplifier in a reception mode, and amplifies a signal to be transmitted using a power amplifier and then outputs the signal by the transceiving antenna in a transmission mode, and the apparatus has a switch connected between the transceiving antenna and the low noise-amplifier, which is turned on in the reception mode and tuned off in the transmission mode, thereby separating transmission and reception signals.

Abstract: PURPOSE: A position tracking apparatus and a method for a low power WPAN/WBAN device are provided to trace the position of a sensor node with low power. CONSTITUTION: A distance collection unit(110) collects the distance information of a plurality of anchor known nodes and each adjacent node to at least one sensor unknown node. A minimum distance calculation unit(120) respectively calculates a shortest path to the anchor node based on the distance information of the adjacent node. The minimum distance calculation unit select the sensor node having the shortest path from the anchor node and minimum distance as a parent node to manage them. A group separation unit(130) divides each node into a first group and a second group according whether their position is known or not. The controller selects a first sensor node nearest to a first group node to find the parent node.

Abstract: An apparatus and a method for estimating a distance using distance estimation counter are provided to measure a distance between a receiving device and a transmitting device of a signal by mathematically calculating an inputted signal. An AD converter(500) converts a received packet signal, and generates a serial digital signal. A parallel part parallels the serial digital signal. 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.
