Abstract
The exponential growth of multimedia users demand fast data rates and reliable transmission which leads us towards fourth generation (4G) wireless technology. In recent years, the adaptive modulation based multi-carrier code division multiple access (MC-CDMA) systems captured maximum attention. In this paper MC-CDMA-TCM is tested over wireless fading channel. The objective of this research is to perform an analytical study of the MC-CDMA-TCM system to achieve theoretical BER curve. A conclusion is drawn on the basis of the outcomes of research which favors the system for better performance over Rayleigh fading channel but the increasing design complexity limits the system to use very high constellation orders.
