Abstract
In 4G systems such as Wimax and LTE, system performance suffers from interferences and lack of low complexity algorithms for interference cancellation as well as utilization of optimal resource. In this paper, we propose a PCINR and EM based optimal resource allocation scheme to improve the performance of 4G systems and compensate the performance loss due to spatial correlation and interferences. Furthermore, the SIC technique is employed to mitigate interferences. The performance of the proposed system is evaluated by computer simulations and is shown to outperform the conventional schemes.
