Analysis of Spectral Efficiency in Downlink OFDMA Femtocell Networks
نویسنده
چکیده
Orthogonal Frequency Division Multiple Access (OFDMA) has been selected as the multiple access technique to meet the growth of cellular subscribers and the need for faster and more reliable data services. The fundamental in OFDMA femtocell network is the interference management. When femtocell is deployed in the existing macrocell network, there will be a chance of interference between the femtocells and macrocells. Therefore a joint subchannel and power allocation method is proposed that reduces interference. The performance of OFDMA femtocell network depends on spectral efficiency. The major focus of this paper is to study the effect of spectral efficiency on network performance.

We consider the joint subchannel allocation and power control problem for OFDMA femtocell networks in this paper. Specifically, we are interested in the fair resource sharing solution for users in each femtocell that maximizes the total minimum spectral efficiency of all femtocells subject to protection constraints for the prioritized macro users. Toward this end, we present the mathematical fo...

متن کاملSelf-optimized Coverage Coordination and Coverage Analysis in Femtocell Networks
This paper proposes a self-optimized coverage coordination scheme for two-tier femtocell networks, in which a femtocell base station adjusts the transmit power based on the statistics of the signal and the interference power that is measured at a femtocell downlink. Furthermore, an analytic expression is derived for the coverage leakage probability that a femtocell coverage area leaks into an o...
