The remarkable technology for seamless integration of wireless and optical networks is radio frequency signals over Free Space Optics (FSO). This research study and simulation examine the design and evaluation performance of Radio Frequency over FSO (RF-F... see more

Satelit nano IiNUSAT merupakan satelit nano pertama yang dibuat dan diluncurkan oleh mahasiswa dari beberapa perguruan tinggi di Indonesia. Riset terkait satelit nano IiNUSAT telah mencapai tahap kedua yang bernama IiNUSAT II. Sistem komunikasi satelit na... see more

Pada sistem komunikasi baik analog maupun digital, suatu sistem komunikasi memerlukan proses modulasi. Modulasi merupakan proses pengkodean informasi dari sumber pesan menggunakan cara yang sesuai dengan proses transmisi. Hal ini dilakukan agar sinyal inf... see more

In this paper we developed a computer based wireless advertising communication system (CBWACS) that enables the user to advertise whatever he wants from his own office to the screen in front of the customer via wireless communication system. This system c... see more

A new modem circuit technique is proposed for multilevel signal transmission to utilisethe transmission bandwidth efficiently in bandwidth-constrained voice-band channels. Usingthis technique, a 16-level quadrature amplitude modulated (16-QAM ) signal is ... see more

Introduction: One of the ways of increasing the noise stability rail circuit is the use more informative waveform of control signal. Use in rail circuit modulated signals gives several informative selective traits in relatively narrow spectrum. The study ... see more

This paper studies the performance of coded orthogonal frequency division multiplexing system using two modulation techniques, quadrature phase shift keying (QPSK) and M-ary quadrature amplitude modulation(M-QAM) with M=8, 16, 32, and 64. The convolutiona... see more
