Abstract :
In this paper we focus on analyzing the performance of spatial channel separation method to mitigate the interference experienced by the macro user equipment (MUE) trapped inside a closed access femtocell for a Long Term Evolution (LTE) system. This is implemented by un-correlating the MIMO (Multi Input Multi Output) channels between each transmitter-receiver pair so that the transmissions of eNB (evolved Node B) - MUE and HeNB (Home evolved node B) - HUE (Home User Equipment) can happen in different spatial channels. This approach works without the macro-femto coordination and further, no feedback information is required. Our simulation study shows that there is a considerable improvement in signal to interference noise ratio (SINR) at the MUE can be achieved.
