In this paper, we propose a new fast frequency-hopping code-division multiple-access (FH-CDMA) scheme, in which prime sequences are used for modulation on top of FH-CDMA. The new prime/FH-CDMA scheme supports higher data rate than the conventional M-ary frequency-shift-keying FH-CDMA (MFSK/FH-CDMA) scheme, at the expense of worsening cross-correlation values. The performance and normalized spectral efficiency of both schemes are analyzed and compared. Our results show that the prime/FH-CDMA scheme, in general, utilizes similar system efficiency as the MFSK/FH-CDMA scheme and that both schemes provide a trade-off between data rate and performance.
