Design and Implementation of Computationally Efficient MC-CDMA Transceiver and Performance Analysis in Fading Channels

This paper describes an optimal design of Multi Carrier Code Division Multiple Access (MC-CDMA) based transceiver in terms of complexity and number of computations for different fading environments. The performance gap between OFDM, MC differential-CDMA and proposed optimal MC-CDMA transceiver is evaluated for spectral efficiency and PSNR in different fading environments and results proved that proposed transceiver provided much efficient robustness against hostile frequency selective fading, high spectral efficiency and frequency diversity. The proposed algorithm was assessed dually in terms of simulations in MATLAB and implementation on DSP kit for real time data.
