  • A modification is proposed to reduce the complexity of Overlap-Cut (OC) method Frequency Domain Equalization (FDE) in Code Division Multiple Access (CDMA) downlink systems. FDE based on Fast Fourier Transform/Inverse Fast Fourier Transform (FFT/IFFT) carries out single-tap equalization on received signal, moreover, its complexity is much lower than its time-domain counterpart. The analysis for the generation and the distribution of the inherent error of OC method FDE indicates some improvement to the equalizer. As a result of both theoretical analysis and simulation, a better performance is obtained with lower computation burden than conventional algorithms.
