    <description descriptionType="Abstract">&lt;p&gt;shaped orthogonal frequency multiplexed (OFDM) modulation is presented. The average symbol energy of probabilistically shaped&lt;br&gt;
OFDM modulation is investigated for different modulation orders of quadrature amplitude modulation (QAM) under different entropy&lt;br&gt;
scenarios. Furthermore, the symbol error performance of the probabilistically shaped OFDM system under additive white Gaussian&lt;br&gt;
noise (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&amp;minus;3. This gain increases to 5.5 dB by decreasing the entropy to 6.80 bits.&lt;/p&gt;</description>
