Carrier Aggregation for Long-Term Evolution (LTE) Advanced Mobile Communication Platform

Abstract

This research implements and evaluates Carrier Aggregation (CA) techniques in LTE-Advanced networks to address escalating mobile data demands. Using LTE Link Layer Simulator in a 4G test bed, we investigate continuous spectrum aggregation at the physical layer, analyzing impacts on Block Error Rate (BER), Signal-to-Noise Ratio (SNR), and throughput. Experimental results demonstrate that aggregated signals exhibit smooth BER-SNR characteristics while maintaining throughput efficiency approaching theoretical limits. The study confirms CA's viability for bandwidth expansion in next-generation networks, though implementation requires careful optimization to balance performance gains against processing complexity. These findings contribute practical insights into LTE-Advanced deployment, particularly regarding physical layer modifications necessary to support multimedia-rich mobile services
