Time-domain signals (a) and corresponding spectra (b) reconstructed via Rx1 under different ON/OFF configurations of Tx1 and Tx2. Time-domain signals (c) and corresponding spectra (d) reconstructed via Rx2 under different ON/OFF configurations of Tx1 and Tx2. The THz time-domain waveforms in (a) and (c) are vertically shifted for clarity.
