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.
