Software-defined radio (SDR) is a programmable transceiver that can work with a variety of wireless protocols without the need for hardware changes or upgrades. Advances in SDR have led to an escalation in protocol development and a wide range of applications with a greater emphasis on programmability, flexibility, mobility and energy efficiency in cellular, Wi-Fi and M2M communications. Consequently, the SDR system has received a lot of attention and is of great importance for both academia and industry. The SDR developers intend to simplify the implementation of communication protocols, allowing researchers to experiment with prototypes in deployed networks. This article provides an overview of SDR and introduces a zero-IF architecture. After that, the simulation of the zero-IF architecture was performed in the MATLAB environment and its implementation on the Altera DE2-115 platform was presented.
