Software-defined radio (SDR)-based adaptive platform design for wireless high-resolution video transmission

Software Defined Radio (SDR) is a technology that replaces traditional hardware-based systems and performs modulation, demodulation, and analysis of radio frequency (RF) signals through software. In this thesis, the design, implementation, and performance evaluation of a system for high-speed data broadcasting using SDR is discussed. Within the scope of the study, the transmitter system was designed with GNU Radio and BladeRF x40; reception and signal analysis were carried out with RTL-SDR and HackRF One devices. The main goal is the successful modulation, broadcasting, and reception of data, followed by analysis by the receiver. The thesis presents practical applications of SDR technology in the field of high-speed data broadcasting, including modulation techniques, signal processing steps, and transmission parameters. In addition, signal quality was analyzed under different operating conditions, taking into account hardware noise and limitations that restrict transmission. The findings show how the transmission process can be optimized for more effective reception and high performance. The results of this study contribute to a better understanding of SDR-based digital broadcasting systems and emphasize the potential role of software-defined solutions in modern communication infrastructures. Moreover, through the implementation of a DVB-T transmitter and receiver, the study provides a solid practical basis for future research on adaptable technologies for broadcasting. The results show how SDR technology can provide important contributions in terms of flexibility and efficiency in next-generation communication networks
