Abstract
The popularity of wireless networks has attracted
the attention of researchers to improve the network system and
this motivated the operators to find a new technology called
femtocells with the aim of meeting the increased coverage and
data demand in the indoor environment.
The application of femtocells in both indoors and office
environment has provided good quality service and high
performance network gains.
However, femtocells face challenges of interference
management which deteriorate the capacity and quality of
network. But to cope with these challenges, many researchers
have come up with solutions to solve the problems, some of
which include interference cancellation and interference
avoidance.
