Abstract

Carrier aggregation (CA) is one of the most important technologies to ensure the success of 4G technologies. This paper presents new Long Term Evolution-Advanced (LTE-Advanced) depending on CA technology; the new system has better performance than LTE. The system supports wider bandwidth up to 120 MHz and provides higher level of throughput. Aggregated LTE-Advanced is designed with 2×2 Multiple Input Multiple Output (MIMO) and different modulation techniques such as: Quadrature Phase Shift Keying (QPSK) and 64Quadrature amplitude modulation (64QAM). The results presentation and comparison prove that the maximum throughput is based on assuming 64QAM data modulation, maximum bandwidth 120 MHz and 5/6 code rates.
