Performance of MC-CDMA Systems with Frequency Offsets Over a Correlated Rayleigh Fading Channel
نویسندگان
چکیده
In this contribution we analyzed and compared the bit error rate performance for MC-CDMA (multicarrier codedivision multiple access) systems using IFFT/FFT (inverse fast Fourier transform/fast Fourier transform) and conventional correlation receiver over a frequency selective Rayleigh fading channel. Carrier frequency offset is considered in the analysis with either equal gain combining or maximum ratio combining. It is shown that the system using IFFT/FFT is more efficient to implement than the conventional one, with only slightly performance loss.
