Abstract

We compared four commonly used interpolation algorithms including linear interpolation, spline interpolation, low-pass interpolation, and time domain interpolation for channel estimation based on pilots in a reversely modulated optical single sideband system with an orthogonal frequency division multiplexing signal. The results show that the spline interpolation method exhibits the best performance.
