Robust Time-of-Arrival Estimation With an Energy Detection Receiver

Free registration required

Executive Summary

In this paper, the authors derive and analyze a novel time-of-arrival estimation rule, which is robust to channel length uncertainty and requires a-priori knowledge of noise variance and signal-to-noise ratio only. This estimator can easily be implemented using the output of a standard energy detection receiver. Moreover, they show by means of computer simulations applying various channel models that the proposed rule outperforms state of the art low complexity time-of-arrival estimation rules in terms of root mean squared error.
