Testing Signal Processing Techniques for Digital VHF/UHF Transceiver in High-level SDR Programming Environment

Abstract

Nowadays, due to cost savings, flexibility or improvement of service quality, modern communication devices solely rely on the digital domain when it comes to signal processing. The paper presents a comfortable, fast and straightforward approach of testing and verifying developed digital signal processing techniques before their implementation into a digital mobile transceiver. The approach benefits from the concept of an Software-defined radio (SDR) by employing a high-level programming environment capable of direct analog radio frequency (RF) front end control in real-time via a user defined software.
