Femtocell architecture involves the use of two separate layers-the macrocell and femtocell
layers. In this architecture, the former is the conventional cellular network, whereas the latter …

Both orthogonal frequency-division multiple access (OFDMA) and femtocell are promising
technologies providing subscribers with better services. However, due to the ad hoc nature …

Femtocells are attractive candidates for future cellular systems since they can greatly
improve coverage and data rates. However, severe interference may occur and hinder the …

We propose a blind interference alignment scheme for partially connected cellular networks.
The scheme cancels both intracell and intercell interference by relying on receivers with one …

Heterogeneous network deployment represents one of the main enhancements of future
LTE-A networks to increase spectrum efficiency. However, the achievable improvements are …

The deployment of femtocells in current and future communication systems promises an
effective solution for limited indoor coverage problem and a possible gateway for mobile …

We consider a heterogeneous Long Term Evolution Advanced (LTE-A) network where a
cognitive femtocell operates in the coverage area of a traditional macrocell sharing the same …

The demand for precious radio spectrum is continuously increasing while the available radio
frequency resource has become scarce due to spectrum segmentation and the dedicated …

Recently, cognitive radio enabled femtocell is regarded as a promising technique in wireless
communications, where the issues of resource allocation and interference management …

This letter propose a novel scheme for cognitive macro/femtocell downlink coordinated
multipoint (CoMP) transmission to improve the capacity of femtocell without affecting the …
