Simulation framework for data transmission by FM radio broadcasting on a two-ray propagation channel

This paper presents a simulation framework intended to perform realistic simulations of point-to-point transmissions in the FM (Frequency Modulation) band. The considered application is the broadcasting of drivers’ warning notifications by the means of low-resolution images (pictograms) embedded into the FM signal. The proposed simulation framework gives the possibility of obtaining an estimation of the communication range. More in details, it is capable of extracting BER (Bit Error Rate) with respect to different communication scenarios while being able to bring realism in the model of different parts of the transmission chain (e.g., down to circuit level). The proposed tool was validated by simulating transmissions with two digital modulation schemes i. e., QPSK (Quadrature Phase Shift Keying) and 8-PSK respectively, and by modelling a LOS (line-of-sight) two-ray propagation channel.
