SDR based Shortwave Receiver

Abstract

This paper deals with proposal of shortwave radio receiver based on SDR (software defined radio). The main objective is to design and simulate shortwave radio receiver RF front-end based on Red Pitaya SDR capable of receiving DRM broadcast. The proposed design utilizes dual-conversion mixing and is able to receive signals from whole DRM spectrum range. Design includes system diagram and schematic of proposed device which was simulated at system level to determine important parameters (SNR, dynamic range, etc.).
