Abstract :
The potential performance of a cellular frequency-hopping code-division multiple-access system is evaluated for both the forward and reverse links. The effects of sectorization, the number of mobile users per sector, spatial diversity, the number of frequency channels, and the thermal noise are studied. The performance advantage of separated orthogonal frequency-hopping patterns, which eliminate the effects of spectral splatter, is demonstrated
