The big challenge at any cellular system is to keep providing Coverage and quality of service. Femto-cells are used to overcome the dead zones problem and an efficient way to improve coverage. By using Cognitive Radio, spectral efficiency can be provided too. In this paper, a Femto-cell integrated over LTE Advanced (LTE-A) macro-cellular system under the effect of the distance between the macro user and the Femto-cell (R) on Signal-Interference Noise Ratio (SINR), Path-Loss (PL) and THRoughput (THR) with changing in bandwidth and the modulation technique are introduced which is not clarified until now.
