| Summary: | The crucial design issues for future wireless transceivers are the challenging and contradictory requirements of high performance, low power, and flexibility. The application requirements for wireless systems are quite diverse in terms of changing data rates and bit error rates along with changing bandwidths and other channel parameters like the delay spread. This paper discusses the effects of FFT on MC-CDMA system, also focusing on determining the optimum number of points for FFT in different situations depending on the used modulation technique. The best size of FFT leads to minimum bit error rate and best system performance. |
