Abstract :Over the past decades, wireless cellular networks has experienced tremendeous evolutional growth. However, providing sufficient coverage and capacity for indoor users has always been a major challenge for mobile network providers. Despite the fact that Long Term Evolution-Advanced (LTE-A) systems facilitate high speed data services, poor indoor coverage and interference still diminish the quality of real-time data services as well as the throughput performance of LTE-A in indoor scenarios. In solving this problem, the study presented in this paper investigates the efficiency of Distributed Antenna System (DAS) in overcoming mobile signal reduction in-door environment. This was achieved by developing two algorithms with and without DAS using tree topology deployment of active DAS. The developed algorithms were then evaluated using some wireless communication performance indices. The performance evaluation result shows that the algorithm with DAS outperforms the one without DAS with improved Bit Error Rate (BER) performance. In addition, the overall performance evaluation result obtained shows that the DAS technologies effectively improve the performance of LTE-A both indoor and outdoor environments.Keywords : DAS, LTE-A
