Carrier Aggregation (CA) is one of the important features of Long Term Evolution-Advanced (LTE-Advanced), which is being standardized in Third Generation Partnership Project (3GPP) as part of LTE Release 10. This study also presents throughput results based on different parameters; Beyond 20 MHz, the only reasonable way to achieve LTE-Advanced highest target peak-throughput rate is to increase the transmission bandwidth, relative to Release 8. This paper presents a novel LTE-Advanced depending on carrier aggregation to get better performance of the system; the simulation is applied with 8X8 Multiple Input Multiple Output (MIMO) LTE- Advanced using different modulation techniques such as: QPSK, 64QAM (Quadrature amplitude modulation) in order to determine the higher throughput to depend it in design; the maximum throughput result is based on assuming 64QAM data modulation, maximum bandwidth 120 MHz and 5/6 code rates.
