Abstract :
In this paper, a proposed technique is used to improve the performance of multi-carrier code division multiple access (MC-CDMA) based fast Fourier transform (FFT). The results are compared with the original technique for MC-CDMA. As a result, it can be seen from the proposed technique that a high performance improvement was obtained over traditional MC-CDMA, where the bit error rate (BER) is widely reduced under the additive white Gaussian noise (AWGN) channel characteristics.
