Simulation of LTE femtocell interference scenarios for cognitive radio implementations

This article presents results of the LTE Femtocell mitigation interference simulations for cognitive radio implementation. The simulations have been performed using the SEAMCAT software at 700 MHz with a 10 MHz bandwidth, considering indoor and outdoor propagation environments. The result is the evaluation of the reduction of cross-tier interference obtained by applying the cognitive radio technology in a femtocell and macrocell network considering different scenarios.
