Deep learning for X-ray communication channel estimation in OFDM-PWM systems

We experimentally demonstrate the channel estimation based on the deep neural networks in the X-ray communication system. By implementing OFDM-PWM modulation, the system achieves a total data rate of 1.14 Mbps with BER of
$9.13 \times 10^{-4}$
over the air-scintillator channel.
