A study on demodulation system design of the VOR receiver

Abstract

In this paper, we studied VOR receiver system designed for digital communication system. A VOR provides the user with a bearing to the station. Digital hardware was used to determine the phase relationship between the two 30Hz signal. The design in this paper acquires the phase of the 30Hz variable and reference signals from the composite audio output of a VOR receiver using DSP and FPGA methods implemented in software. VOR signal generator using a frequency 108MHz, -70dBm to receive input power to the system, the developed system was verified by operation. © 2011 Springer-Verlag.
