Method for Ranging Between Transmitter and Receiver Based on Wireless Communication System

摘要

The present invention relates to a radio communication based transmission, the receiving apparatus between the distance estimation method, a multiple signal classification narrow-band linear frequency modulated chirp, or between each node to apply to the signal sent from the indoor environment, the radio communication based song that can measure the distance between the receiving apparatus, to provide a method for estimating the distance between the receiving device. ; The technical configuration is the first step of transmitting a transmission signal in a wireless communication system based on a chirp modulation transmission apparatus to the reception apparatus; Sending, receiving and summing the time-delayed, but each of the transmission signal reflected by the multi-path propagation path between the reception device, the second step of applying a damping and noise for each path; For the transmitted signal and the received signal multiplied by the frequency estimate of the complex signal, a third step of calculating a pseudo spectrum using a multiple signal classification method; A fourth step for calculating a time delay according to the frequency of the lowest frequency that make up the peak that occurs in the search, and this pseudo spectrum; By multiplying the propagation time delay in transmission speed, a fifth step of calculating a distance between the receiving apparatus; Comprises a.
