Abstract
The authors investigate the Erlang capacity for reverse link in cellular mobile networks using an overlapped carrier CDMA (OC-CDMA) which is defined as a variation of FD (frequency division)/DS-CDMA where overlapping between adjacent carriers is permitted. Numerical results demonstrate that up to 49.6% of the Erlang capacity increase is achievable in certain circumstances with the conventional power control scheme. Finally, a sophisticated power control scheme is proposed, which takes into account the number of active users in adjacent carriers to achieve a higher Erlang capacity gain
