Abstract :
An Hermite-symmetric subcarrier coding for OFDM systems (HC-OFDM) enables dual channel transmission over individual IQ wireless channels with higher power efficiency than a simple repetition coding (RC-OFDM). We theoretically proved the advantage of the HC-OFDM systems assuming an ideal coherent detection. But, in practice, the dual channel transmission needs precise phase compensation to separate each channel. In this paper, we evaluate the robustness against fading fluctuation in the HC-OFDM systems.
