| Summary: | The use of mobile devices has gradually increased over time. It has become a necessity
for people to own mobile devices in order to communicate with others all around the
world. With increasing number of users, the LTE network service providers need to think
of a way on how to enhance their service so that users can experience faster internet
experience without any disruption from the network. In a heterogeneous network that
consists of several base stations and scores of users, cross-tier interference is bound to
occur. Cross-tier interference can cause loss of signal and drop calls. In this paper, a
Dynamic Spectrum Allocation (DSA) technique was proposed and implemented in a LTE
network configuration. At this juncture, the study only focuses on the segment involving
communication downlink. Software development toolkit GNU Radio was used in the
assembly of the network configurations. Throughput comparison was then made against a
normal LTE network configuration. The throughputs of both configurations were
computed and assessed. Configuration embedded with DSA managed to achieve higher
throughput. The findings suggest that DSA is a technique capable of mitigating
interference for LTE network. |
