A wireless communication experiment that uses photonic-assisted radio-frequency arbitrary waveform generation (RF-AWG) for precompensation of multipath distortion over a 2–18 GHz frequency band is reported. Photonic-assisted RF-AWG is used both for spread spectrum sounding of the multipath chan- nel and for synthesis of precompensation waveforms that yield pulse compression and distortion suppression at the receiver. By directly encoding the precompensated waveforms in optical hard- ware, 250 Mbit/s error-free data transmission is achieved experi- mentally in binary-phase-shift-keying format. For the first time to our knowledge, phase compensation and time reversal precompen- sation techniques are compared in hardware encoded data trans- mission experiments; our results confirm predictions that phase compensation outperforms time reversal under intersymbol inter- ference limited conditions.
