Abstract:

Femtocell is the micro base station for solving the problem of mobile communication coverage indoor, which can serve indoor users with high speed broadband at a relatively low power. It can solve the indoor communication coverage problem in city life. Femtocell will become the one of the main means of indoor communication service in the future. However femtocell is facing the great challenges of communication interference management as other communication equipment. The normal interference technologies with femtocell under MIMO, OFDM and OFDMA system were firstly introduced, and then the background of interference problem in femtocell was introduced. Finally, according to the characteristics of the femtocell deployment, its interference suppression methods were summarized and compared.

Key words: femtocell, interference suppression, multiple-input multiple-output, orthogonal frequency divisionmultiplexing
