Figure 6

Operation of demodulation demonstrated for the 2 m single-channel ‘THz Torch’ wireless link field trial. (a) NTM with initial thermal emitter parameters (16 symbol errors). (b) NTM with calibrated thermal emitter parameters (7 symbol errors). (c) MF with initial thermal emitter parameters (9 symbols errors). (d) MF with calibrated thermal emitter parameters (error free). The LSTM-based demodulator with and without calibrated thermal emitter parameters (error free) is also shown in (c,d). Here, the LSTM-based demodulator is only trained on the simulated dataset without any fine-tuning using data from the real system.
