A Bilevel Frequency Hopping CodeDivision MultipleAccess (FHCDMA) scheme for wireless communication systems is developed. This new scheme provides flexibility in the selection of modulation codes and FH patterns. By partitioning modulation codes, our BiLevel FHCDMA scheme can be modified to support more possible users without increasing the number of FH patterns. This scheme is applied for different Fading channels and their performances in terms of Bit Error probability (BEP) are compared. We also calculate Spectral Efficiency (SE) of this scheme and compare this with Spectral Efficiency (SE) of Goodmans FrequencyShiftKeying FHCDMA. Our results show that the partitioned TwoLevel FHCDMA scheme supports higher data rate and greater SE than Goodmans FrequencyShiftKeying FHCDMA scheme under some conditions.
