Abstract :
We propose an algorithm for CO-OFDM receivers to perform overlapped frequency-domain CD and PMD equalization before OFDM symbol demodulation. This approach enables OFDM transmission with a small cyclic prefix overhead of only 0.08%, and can enlarge the frequency averaging length for channel estimation in the presence of high PMD.
