East-West Design & Test Symposium, 2020
Presented research is dedicated to the gradual transition from analogue types of railway radio communications to digital radio standards, mainly to the DMR standard. It was found that there is a lack of theoretical basis for this problem. The article set

Optical Fiber Communications Conference and Exhibition, 2021
We propose and experimentally demonstrate a hybrid digital-analog radio-over-fiber technique based on cascaded digital PCS-121-QAM modulation and analog pulse code modulation for each radio waveform sample, achieving 12.8 dB SNR gain over A-RoF and 1.38%
