Abstract
Problem. The multifactor distortions inherent in HF radio channels pose significant challenges in designing effective signal processing systems that ensure reliable information transmission. Addressing this issue requires the development of HF communication link simulators capable of diagnosing channel conditions and interference. Leveraging client-server control technology presents promising new avenues for enhancing communication channel diagnostics.
Objective. This study aims at developing an ionospheric HF radio link simulator utilizing GNU Radio technology and a client-server methodology to manage the system effectively.
Findings. The study presents a novel approach and hardware-software implementation of an ionospheric HF radio link simulator based on GNU Radio technology, incorporating client-server control. The simulator models the transmission and reception of spread spectrum communication signals within the GNU Radio environment. Key algorithms implemented include the synthesis of the emitted spread spectrum signal and the digital processing of the received signal. Experimental testing validated the simulator's ability to accurately replicate the transmission characteristics of HF radio links. The developed simulator serves as a practical test model for HF radio communication links, supporting the design of radio engineering systems that utilize diverse coherent signal reception.
Practical significance. The HF radio link simulator offers a valuable tool for testing and developing radio communication systems, particularly those involving diverse coherent signal reception.
