Abstract

We investigate the problem of joint frequency offset and channel estimation for an 112 Gbit/s QPSK CO-OFDM system. The paper presents a novel joint frequency offset and channel estimation method based on CP and training symbols. Simulation results indicate that even OSNR is very low, it estimates frequency offset and channel response very well.
