Perbandingan Kinerja Non-Orthogonal dan Orthogonal Amplify and Forward pada Two-Way Cooperative WLAN
Abstract: Nowadays, the
advancement of Wireless Local Area Network (WLAN) technology has developed very
rapidly because it is very practical and has effective mobility level. In
practice, there is a major problem in wireless communications systems, which is
fading. Fading can cause information signal power decreasing. Fading can be
overcome using a cooperative communication system, which is a method that
utilizes antenna from other users (relays), using principle of diversity, hence
the performance of wireless communication system is improved. A relay has
several protocols on cooperative communication system, such as Amplify and
Forward (AF), Decode and Forward (DF), and Compress and Forward (CF). The AF
protocol is divided into two types: Non-Orthogonal Amplify and Forward (NAF)
and Orthogonal Amplify and Forward (OAF). In this paper, the performance
comparison of two-way NAF and OAF in terms of outage probability, throughput,
and spectral efficiency is investigated. The method used is computer simulation
with system modeling and performance analysis. The simulation results show that
OAF protocol can minimize outage probability and increase throughput and
spectral efficiency, compared to NAF protocol on two-way WLAN cooperative
network.
