Figure: Local-mean Bit Error Rate for MC-CDMA versus Eb/N0 in a dispersive Rayleigh-fading channel with independent fading at adjacent subcarriers. Synchronous downlink with spread factor N and N simultaneous users. Receiver: adaptive wiener filtering.
(1) Analytical expression for infinitely many subcarriers
(2) 64 subcarriers (N = 64)
(3) Single subcarrier, same result as average BER in slowly fading, non-dispersive Rayleigh fading channel
(4) Standard erfc function for AWGN LTI non-dispersive channel
