Measurement of non linear thresholds in O-OFDM systems with respect to data pattern and peak power to average ratio

We investigated the non linear threshold of a coherent O-OFDM system. An improvement for NLT of about 2.5 dB was demonstrated either by reducing the data pattern length or clipping of the OFDM signal.
