摘要：Long Term Evolution-Advanced (LTE-A) has brought revolution in the field of wireless communication technology by providing high data rates of up to 1Gbps. One key enhancement feature of LTE-A is bandwidth extension by the use of multi-carrier technology to support deployment bandwidth of up to 100MHz. To achieve such high data rate in IMT-Advanced mobile systems, carrier aggregation technology by 3GPP has been introduced to support very-high-data rate transmissions over wide frequency bandwidth in the new LTE-Advanced standards. This work includes the details of Downlink LTE Advanced System Model and thereby all the performance analysis of Non Contiguous Carrier Aggregation are done and an overview of LTE-Advanced CA scenarios is discussed. Also component carrier parameters and oversampling factor are found and using these parameters power spectrum is plotted. The main outcome from this work is increase in the throughput of the system by increasing the number of carrier components or by increasing bandwidth. Many proposals on carrier aggregation in LTE-A have been published but still there is a need of research to be carried out in this field as this technology has not fully matured
