dc.description.abstractWe propose a technique for simultaneously transmitting two signals with different waveforms (non-return-to-zero on-off keying (NRZ-OOK) signal and discrete multi-tone (DMT) signal) in an optical wireless link based on visible light emitting diode (LED). A sparse compressive sampling technique is proposed to reduce the length of the DMT signal encoded by quadrature phase shift keying (QPSK) symbols and a derivative-subtractive sampling is proposed to separate the NRZ-OOK signal and the DMT signal from the mixed signal (NRZ-OOK + DMT). It is possible to reduce the length of the DMT signal up to 38% using the sparse compressive sampling technique. A 37.6-Mb/s transmission capacity (NRZ-OOK: 10 Mb/s, QPSK symbols: 20 Mb/s + 7.6 Mb/s) is achieved over 10 ­MHz bandwidth.en
