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...

| description | 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
the same minimum distance 2d. Simulation works for Fourier
and wavelet based OFDM have been performed. In Fourier
base OFDM, the circular has slightly out-performed the square
when the number of subcarriers is varied from 32 to 256 at
different BER values. When considering wavelet based OFDM, all
wavelet families except Biorthogonal and Reverse-Biorthogonal
have performed similar result for both modulation schemes. Of
all Biorthogonal families, bior5.5 is the most out-performed one
when using circular and square 16-QAM respectively. |
