R = B / T Basic steps: We estimate the delay by estimating the frequency shift between the received and transmitted signal. Typically the resolution of a frequency estimate is the inverse of the observation time, which in this case is 1 / T. Why? Think of taking the Fourier Transform of a tone with a rectangular window T.
