This paper presents an analytical evaluation of a direct-sequence/frequency-hopped code
division multiple access (DS/FH-CDMA) system employing non-coherent multiple tone
frequency shift keying (MT-FSK) modulation in a Rayleigh fading environment. Multiple-
tones per symbol rather than single tone per symbol (as in conventional MFSK) is used to
provide diversity in a frequency selective channel. In the performance evaluations, multiple
access interference (MAI) has been taken into account and the capacity for uncoded as well …
This paper presents an analytical evaluation of a direct-sequence/frequency-hopped code division multiple access (DS/FH-CDMA) system employing non-coherent multiple tone frequency shift keying (MT-FSK) modulation in a Rayleigh fading environment. Multiple-tones per symbol rather than single tone per symbol (as in conventional MFSK) is used to provide diversity in a frequency selective channel. In the performance evaluations, multiple access interference (MAI) has been taken into account and the capacity for uncoded as well as convolutionally coded systems have been calculated.
