| Abstract(in English) | This paper proposes Code Frequency Division Multiple Access(CFDMA)generalized from Coherent Hybrid DS-FFH CDMA,and derives various types of transmission channels from CFDMA.Among CFDMA,Interleaved Frequency Hopping(IFH)is superior to the others in tracking the fading,and computer simulation verifies the performance.In fading channels,IFH of chip number K=2 achieves average BER of 10^-2> at 15 dB average E_b, N_O and 60 Hz maximum Doppler frequency f_D under full co-channel interference condition. IFH of K=4 achieves the BER at f_D=300 Hz under half co-channel interference condition. |
