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 ...
Abstract: Data transmission over power lines as a medium for information transmission over a traditional grid system is a relatively new area of telecommunication. This study investigates one of the ...
