DISTANCE ASSUMPTION APPARATUS, SYSTEM AND METHOD USING RANGING COUNTER

摘要

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.
