In this research, the mobile network is designed with several layers of small and large cells in the heterogeneous network. This architecture is faced with the task of supply allocation (power, channel, time) for small cells in order to guarantee reliable and high-quality service to both primary (macro-cell) users as well as secondary (femtocell) users. Intra-tier femtocell interference is dealing with minimum mean squared error (MMSE) interference in Rectangular antennas that this proposed two-tier interference management approach improves the performance of the femtocell users in between multiple users, by maintaining the desirable quality of the communication channel for macro-cell users. In proposed scheme by using Rectangular patch, antenna will react as in multiple input multiple output band for femtocell user. The frequency sub bands which are presently not recycled within the macro-cell, so the process is based on FFR for assigning the frequency bands. The simulation results show that the proposed approach gain for macro-cell and small cell tiers, in terms of average Signal to noise improving up to 37.2 dB that is virtual to the non-cooperative case, which is for a network with 350 SBSs and 200 MUEs which is improvement in higher spectrum sensing for MUE’S.
