  abstract = {In recent years, CDMA becomes most widely used spread spectrum technique in wireless communication
system because MC-CDMA allows multiple users to share the same frequency spectrum simultaneously. In this paper,
generating an input signal and modulating it using MC-CDMA is the primary work. After the modulation of signals,
different noises are added to the modulated signal and checking the received signal, BER, SNR. To check the fidelity of the
transmitted signal, noises are added because when the signal is generated in the transmitted channel and the signal is affected due to noises. The reasons of these improvements have been explained analytically and the simulations results
with the verified analytical results. There are several modulation schemes such as BPSK, QPSK and QAM. Modulation schemes are used in conjunction with MC-CDMA technique to provide different data rates to fulfil the requirement of
different application. In MC-CDMA system signals arrive at the receiver from multiple paths due to reflection, diffraction and scattering which results in signal fading and degrade the performance of the system.},
