Abstract

“DESIGN AND SIMULATION OF DOUBLE SIDE BAND SUPPRESSED CARRIER MODEL USING MATLAB SIMULINK TOOL AND EFFECT OF NOISE ON SIMULATION RESULTS USING MATLAB CODING”

*Susanchi Raut, Shivani Umredkar and Prof. Kanchan Wag

ABSTRACT

For long distance communication efficient and effective transmission plays a vital role for which modulation techniques are required. In conventional AM transmission, the sinusoidal component at the carrier frequency which does not contain information and both the side bands (upper sideband and lower sideband) are present i.e., DSB-AM. Therefore, the presence of carrier results in 2/3rd power loss. In order to overcome this problem the carrier signal is suppressed, i.e., removed producing double-side band suppressed carrier (DSBSC). In DSBSC real information is preserved and power wastage is prevented. In this paper more emphasis is on the design and simulation of DSBSC modulation and detection using the Simulink tool of MATLAB. This paper also talks about the effect of noise on simulation results.
