Bit Error Probability for Wireless Communication by Using a Two Level FH-CDMA Scheme Over Fading Channel
Here mainly discussing 'Two-level' Frequency Hopping Code Division Multiple - Access(FH-CDMA) scheme for wireless communication systems and this scheme provides flexibility in the selection of modulation codes and FH patterns. By partitioning the modulation codes, the authors' two-level scheme can be modified to support more possible users without increasing the number of FH patterns. The performance and Spectral Efficiency (SE) of the scheme are analyzed. And results shows that bit error probability for two level FH-CDMA scheme over fading channels that is AWGN, Rayleigh and Rician channels.
