| dc.description.abstract | Mobile broadband services are undergoing a period of dramatic growth causing a tremendous increase in data tra c. One main reason for this rise of tra c is being driven by the growing number of mobile subscribers. This increment in data tra c is handled by new technologies. LTE-Advanced extends the capabilities originally de ned in LTE to increase data throughput by using a combination of new technologies, like Orthogonal Frequency Division Multiple Access (OFDMA), Carrier Aggregation (CA) and Multi Input Multi Output (MIMO) techniques. CA is one of the most signi cant LTE-Advanced features that combine multiple Component Carriers (CCs) across an available spectrum to create a wider bandwidth channel for increasing the network data throughput and overall capacity. This thesis analyzes throughput enhancement using CA technique, by conducting radio propagation using WinProp and system level simulation using Matlab, for di erent CA scenarios of a selected high tra c area in Addis Ababa city, Ethiopia. The addition of 10 MHz CC over 20 CC provides 49%, and 20 MHz provides 105% throughput gains at cell center for case of 1800 MHz (band 3). All the three frequency bands (1800 MHz, 2600 MHz (band 7) and 3700 MHz (band 43)) with two 20 MHz CC provide over 100% throughput gain at the cell center, compare to 1 CC at 1800 MHz. When using low frequency bands, such as the 1800 MHz band, the Signal to Interference and Noise Ratio (SINR) value is low thus providing a better throughput from the cell center to edge. | en_US |
