"description": "<p>shaped orthogonal frequency multiplexed (OFDM) modulation is presented. The average symbol energy of probabilistically shaped<br>\nOFDM modulation is investigated for different modulation orders of quadrature amplitude modulation (QAM) under different entropy<br>\nscenarios. Furthermore, the symbol error performance of the probabilistically shaped OFDM system under additive white Gaussian<br>\nnoise (AWGN) channel condition is evaluated. The probabilistically shaped OFDM system outperforms the uniformly distributed in the symbol error ratio performance. For 256-QAM with an entropy of 7.84 bits, we have shown a 3 dB gain in signal-to-noise ratio (SNR) per symbol compared to uniform 256-QAM at a symbol error ratio of 10&minus;3. This gain increases to 5.5 dB by decreasing the entropy to 6.80 bits.</p>",
