Abstract: Backscattering communications have been recently proposed as an effective enabling technology for massive Internet of Things (IoT) development. A novel application of backscattering, called ambient backscattering (AmBC), has been gaining much attention, wherein backscattering communications…

Abstract: Orthogonal frequency division multiplexing (OFDM) signals with rectangular pulses exhibit low spectral confinement. Shaping their power spectral density (PSD) is imperative in the increasingly overcrowded spectrum to benefit from the cognitive radio (CR) paradigm. However,…

Abstract: All-optical wavelength conversion for 2×11.64 GBaud adaptively-modulated orthogonal frequency division multiplexing (AM-OFDM) signals with QPSK/16QAM formats is experimentally demonstrated in a silicon waveguide. The AM-OFDM signal with partly higher- (and lower-) order formats on lower-…
