Peningkatan Unjuk Kerja Sistem Transmisi Komunikasi Digital pada Penerima dengan Menggunakan Teknik Diversity Equal Gain Combining

Abstract

In digital communication systems, the presence of fading and noise in the channel will disrupt or degrade the performance of digital communication system. This disruption may cause error on signal detection and may cause bits change or symbols at the receiver. By applying Equal Gain combining diversity techniques at the receiver, it can improve the digital communication system performance. Through simulation, this study analyzed the effect of applying equal gain combining diversity techniques on the system that affected by noise AWGN and Rayleigh fading. Performance evaluation on the use of equal gain combining diversity technique can be determined through BER analysis. The simulation result of this study indicates that there is improvement on system performance at the receiver twice better than without utilizing equal gain combining diversity technique.
