  Abstract

In this Paper, a study is conducted on the timing offset estimation for pilot based underwater CSS communication that uses chirp signals utilized for low-power IoT communication. The effect of timing offset on the CSS system is analyzed under a fast-varying underwater acoustic channel. In order to overcome the fast-varying timing offset, a pilot based underwater CSS communication system, and the estimation and compensation algorithm for timing offset are proposed. The performance of the proposed system is numerically analyzed under AWGN and underwater Bellhop channel. It is verified by the numerical analysis that the proposed system is capable of low-power underwater communication even in a low SNR environment of 0dB or less with hpresence of fast-varying timing offset.
