In this book, there are six proposed models of MC- CDMA based on Fast Fourier Transform (FFT) and Wavelet Transform (WT) were introduced and their performances were compared with the traditional models for single user system. The proposed models are based on generating phase matrix rotation algorithm. The first three models for MC-CDMA rely on FFT algorithm. The simulation performance of these models shows that the suggested models improved their performances in AWGN and the flat fading channel in comparing with the traditional model. The other three models of MC-CDMA rely on wavelet transform...
In this book, there are six proposed models of MC- CDMA based on Fast Fourier Transform (FFT) and Wavelet Transform (WT) were introduced and their performances were compared with the traditional models for single user system. The proposed models are based on generating phase matrix rotation algorithm. The first three models for MC-CDMA rely on FFT algorithm. The simulation performance of these models shows that the suggested models improved their performances in AWGN and the flat fading channel in comparing with the traditional model. The other three models of MC-CDMA rely on wavelet transform, especially in In-Place Wavelet Transform. This type of wavelet transform does not require an additional array at each sweep, this leads to fast processing time and minimum memory size relative to the traditional model based wavelet transform. The results show that these models outperform the traditional models under different channel characteristics with high gain obtained from each model.
