A variety of wide band wireless systems have been pushed towards their limits in order to meet growing interest for high data rate in wireless communications.In particular, the limit due to the spectrum scarcity forces communication systems to utilize the spectrum resource at maximum efficiency level. One of the methods that allow effective spectrum employing is to cover multiple systems over same spectrum source by allowing bearable interference to occur between them. Femtocells have been recently introduced as a remedy to spectrum scarcity and coverage problems in current cellular structures. Femtocells are personal use base stations and they share the spectrum in a way that they can coexist with the macrocell. This thesis provides a critical reviews of different access methods in femtocell networks and further introduces improvements related to these access methods. Simulation results validate capacity improvement of proposed techniques compared to the existing access methods.
