| Abstract | In this project, we propose a “two-level” frequency hopping code-division multiple-access (F HCDMA) scheme for wireless communication systems. Th e new scheme provides flexibility in the selection of modulation codes and FH patterns. By partitioning t he modulation codes, our two-level scheme can be modified to support more possible users without inc reasing the number of FH patterns. The performance and spectral efficiency (SE) of the scheme are analyzed . Our results show that the partitioned two-level FHCDMA scheme supports higher data rate and greater S E than Goodman’s frequency-shift-keying FHCDMA scheme under some conditions. |
