Abstract EN
Wireless digital communication networks are rapidly expanding resulting in a demand for reliable and high spectral efficiency systems.
Multi-Carrier Code Division Multiple Access (MC-CDMA) has emerged recently as a promising candidate for the next generation broad-band mobile networks.
Also it was found recently that Radon-discrete wavelet transform (DWT) based Orthogonal Frequency Division Multiplexing (OFDM) is capable of reducing the Inter Symbol Interference (ISI) and the Inter Carrier Interference (ICI), which is caused by the loss of orthogonality between the carriers.
Radon-DWT-OFDM can also support much higher spectrum efficiency than Fast Fourier Transform-based OFDM (FFTOFDM).
In this paper a novel Radon-DWT-MC-CDMA transceiver design will be presented based on the Radon-DWT-OFDM that is used as a basic building block in the design of MC-CDMA transceiver to increase the orthogonality against the multipath frequency selective fading channels.
Simulation results are provided to demonstrate the significant gains in performance and simplicity due to the proposed technique.
The Bit Error Rate (BER) performance of the proposed Radon-DWT-MC-CDMA scheme was compared with that of FFT based MC-CDMA ; Radon based MC-CDMA, and Discrete Multi wavelet Transform (DMWT) based CDMA and tested in AWGN, Flat fading and Selective fading channels.
The simulation results showed that proposed system outperforms the other systems
