Abstract:
The long term evolution (LTE) project was initiated in 2004 motivated by the need to reduce the
cost per bit. And the flexible use of new and the existing frequency band. LTE-Advanced is the
project named of the evolved version of LTE that is being developed by the 3GPP.LTE
Advanced offers considerably higher data rates than even the initial releases of LTE. While the
spectrum usage efficiency has been improved, this alone cannot provide the required data rates
that are being headlined for 4G LTE Advanced. So as to accomplish higher data rates and
efficiently utilize the available resources to design good channel with QOS the using CA and
MIMO is the best solution for growing number of subscribers and good transmission. This thesis
focusing on CA stands for Carrier Aggregation enables greater speeds because it allows you to
download data from multiple sources at the same time. Instead of connecting to the best signal in
your vicinity, your smartphone can combine multiple signals, even on different frequencies. Up
to five of these ―component carriers,‖ each offering up to 20MHz of bandwidth, can be
combined, which creates a maximum aggregated data pipe up to 100MHz and MIMO stands for
Multiple Input Multiple Output, and it can increase the overall bitrate by transmitting two (or
more) different data streams on two (or more) different antennas. All this accomplished by using
MATLAB software program which simulate the performance enhancement of LTE-Advanced by
using CA and MIMO techniques
