Abstract

The performance is investigated of cellular hybrid FD/CDMA (frequency division/ code division multiple access) with the overlapped carrier allocation (OCA) scheme in the reverse link of a cellular radio system. Of primary interest are the effect of chip waveform, the number of carriers and the degree of overlapping between adjacent carriers on the system capacity. To take into account the bandlimited waveform, the analysis is conducted in the frequency domain. It is shown that OCA compensates for capacity loss incurred in the subdivision of the available spectrum for frequency division multiplexing, and that it also achieves even higher capacity for chip waveforms with a smooth spectral shape at no extra system complexity while the merits of FD/CDMA are still fully exploited
