Abstract :
The femtocell is a recommended solution to the indoor coverage and throughput problem. In this paper, we study a scenario with only one femtocell access point, one subscriber and N nonsubscribers in CDMA system. Considering the limitation of the backhaul throughput and all the users´ benefits, we design a novel femtocell open access mechanism based on the greedy algorithm. The analysis and simulations suggest that our mechanism brings profit to both the subscribers and the nonsubscribers, and increases the system throughput at the same time. The simulations also imply that this flexible mechanism outperforms closed access and hybrid access mechanisms.
