N2 - The paper presents a sampling method that dramatically improves the measurement accuracy of the round trip time (RTT) measurement in digital communication systems. For state of the art methods, the accuracy of time measurements in discrete time systems and low noise scenarios is limited to the sampling period T. If the measurement is repeated m-times, the upper bound of the quantization mean square error (MSE) is ~1/m. The proposed sampling scheme reduces the upper bound of the MSE to ~1/m2. This exceptional feature is enabled by applying a prime relation between sampling rate and bit rate of the communication system.
