Abstract
The outage probability is investigated in cellular FD/CDMA (frequency division/code division multiple access) in terms of the SNR under the overlapped carrier allocation scheme in the reverse link of a cellular radio system, which is based on using Gaussian and lognormal approximations, respectively. In numerical results, the bandlimited pulse generated by raised cosine pulse shaping filters (SRRC) of the transmitted signal is investigated and compared in conventional FD/CDMA and OC-CDMA (overlapping carrier CDMA) for the outage probability. It is also shown that the outage probability can be improved by overlapping of carriers.
