Abstract
There is provided a receiver for processing a ranging channel. The receiver includes a Fourier transformer for transforming a received signal into a frequency domain signal, a ranging channel extraction and ranging code elimination unit for extracting a ranging channel from the frequency domain signal, and eliminating a code of a ranging code from the ranging channel and a ranging channel processor for estimating transmission delay or transmission power from a time domain signal. By estimating transmission delay and/or transmission power in a time domain, it is possible to rapidly and accurately adjust the transmission delay and transmission power intensity in the ranging procedure.
