Abstract :
The factor of CFO (carrier frequency offset) definitely degrades the final results of system performance evaluation for an asynchronous MC-CDMA (multi-carrier coded-division multiple-access) system is one of the most frequently discussed issues in every kind of assuming situations. However, the other one important parameter of FBC (fading branch correlation) is much rare for implying in the study of MC-CDMA system, since they are almost considered as independent between the subchannel for the reason of algebra simplification. The issue of exploring aggregately to the matter of which parameter, CFO or FBC, is mainly dominating the system performance of an MC-CDMA system is studied in this paper. Furthermore, the properties of random in generation of CFO and FBC, which are given with the symbols of ε and λ, respectively, are taking simultaneously into account to calculate the system performance with BER (bit error rate) for an MC-CDMA system.
