Abstract :
The CO-OFDM is sensitive to noises and dispersion, so the channel estimation becomes a key issue in performance improvements. An effective method based on LMMSE can compensate the losses more accurately than LS. It can bring in 2dB SNR gains compared with LS under the condition of BER = 10−4.
