Conference paper

Frequency Domain Training-Aided Channel Estimation and Equalization in Time-Varying Optical Transmission Systems

In 2012 Ieee Photonics Conference (ipc) — 2012, pp. 455-456

We propose a non-weighted feed-forward equalization method with filter update by averaging channel estimations based on short CAZAC sequences. Three averaging methods are presented and tested by simulations in a time-varying 2×2 MIMO optical system.
