Improving the efficiency of LTE-MIMO performance by utilizing Carrier Aggregation method

Smart electronic gadgets are used to increase the data usage in recent mobile communications. But, the spectrum efficiency cannot be increased in terms of data rates in 4G LTE. To improve this high data rates, it is essential to improve the bandwidths (≤ 100 MHz) using multiple carrier or channel since it is not possible by single channel or carrier. For improving data rates high, here it is utilized the Carrier Aggregation-[CA] method which aggregates more than two component carriers from the continuous [or Intraband continuous] components in the spectrum. With CA, single user equipment on multiple carriers can be scheduled concurrently, which fulfills the huge set of bandwidth necessities to attain the service for amended performance. Since CA is a multi-carrier method any available SCC-[Secondary Component Carrier] can be combined with the PCC-[Primary Component Carrier], which is allocated to the user equipment. For example, five component carriers each of 20 MHz are combined to increase bandwidth to 100 MHz for high data rates. The extensive simulation is carried out in MATLAB software and the performance of the CA method utilization for LTE-MIMO is presented.
