PERFORMANCE ANALYSIS OF WIDEBAND CDMA SYSTEMS IN A LOGNORMAL FADING CHANNEL
ABSTRACT
In this letter, the performance of a wideband CDMA system in the presence of Lognormal fading is studied. The wideband CDMA system, modeled using Gaussian Approximation is analyzed on a slow fading Lognormal channel which fades the amplitude of the transmitted signal according to the Lognormal Distribution. In the Lognormal fading channel, simulated results are obtained for the following cases: (i) Bit Error Rate (BER) versus signal-to noise ratio (SNR in dB) for a fixed value of channel memory, (ii) BER versus SNR (dB) for different values of channel memory, but a fixed value of user 0 power, and (iii) BER versus SNR (dB) for different values of user 0 power, but a fixed value of channel memory.
