Abstract

The Software Defined Radio (SDR) is an advance type of radio communication system. This paper proposes development of a beacon receiver using software defined radio for processing Ka band satellite signals. GNU radio, a free software tool kit, will be used to develop the beacon receiver functionality. The beacon receiver would be used to detect and measure the signal strength of a transmitted beacon signal. The beacon signals are well suitable for propagation measurement due to stable transmitted power and frequency, and also measures the weather data and radio meter. The hardware components needed for this research are parabolic antenna, a low noise block converter, an ETTUS Universal Software Radio Peripheral (USRP) and Linux PC. This beacon receiver would have low cost compared to commercially available analog receivers. Low Noise Block Converter (LNB) is used to convert the incoming Ka band radio frequency signal to L band intermediate frequency. Ka band suffers attenuation due to rain. Beacon receiver is a high performance receiver and it is used to track the power density of the satellite beacon in real time applications. The signal processing blocks are written in C++ and Python to realize SDR.
