Power Control Research For Home Femtocell Network

As the fast development of the modern mobile communication technology, Femtocell begins toappear. Femtocell is a named “home base station” which can improve both indoor coverage andsystem performance.At the same time,it can decrease macrocell communication overhead. However,the leakage of signal has an effect not only on the indoor users,but also on the outdoor users.This paper analyzes the transmit power control of home Femtocell in the downlink,and gives thepower control algorithms based on unwanted incidents.After that,it improves the formulas and themethods used,making the rate of convergence faster and steadier.In this paper,we first give the model of Femtocell with licenced indoor users and unlicencedoutdoor users,then analyze parameters which affect the power control,and give the algorithms.Atlast, Matlab simulations validate the algorithms,and compare the performances of differentalgorithms.
