An optimal circular 16-QAM modulation technique for wavelet and fourier based OFDM

Abstract—A new approach of an optimal 16-QAM modulation has been introduced to be used for both Fourier and wavelet based OFDM. The comparison between circular and square 16- QAM is included. It is shown that the power consumption of circular is better than the square by 0.5359 W or -2.71 dB for...
