Resource Allocation in Spectrum-Sharing OFDMA Femtocells With Heterogeneous Services

Femtocells are being considered a promising technique to improve the capacity and coverage for indoor wireless users. However, the cross-tier interference in the spectrum-sharing deployment of femtocells can degrade the system performance seriously. The resource allocation problem in both the uplink...
