Abstract :
This paper, we present the evaluation of outage probability on the SNR under the overlapped carrier allocation scheme in the reverse link with imperfect power control of a cellular CDMA system, which is based on using Gaussian approximation. In numerical results, the band limited pulse generated by square-root of raised cosine pulse shaping filters (SRRC) of the transmitted signal is investigated and compared in conventional FD/CDMA and OC-CDMA of the outage probability. It will be also show that the outage probability can be improved by overlapping of carriers. We use the error statistics to model the intracell interference and evaluate the impact of different mobiles velocity and number of resolvable paths on the system performance.
