ANALYSIS OF HYBRID, COHERENT FDMA CDMA SYSTEMS IN RICEAN MULTIPATH-FADING/

This paper extends the analysis presented in [1] of a hybrid frequency division multiple access/code-division multiple-access [FDMA/CDMA (F/ CDMA)] system in a Rayleigh fading environment to include the presence of a direct-path component (i.e., Ricean fading). The results show th at a ''wideband'' CDMA system out performs a hybrid system, although t he combination of a specular component and an exponentially decaying m ultipath intensity profile (MIP) with a large decay factor may result in only a minimal degradation of system performance for a hybrid syste m.
