Item5.36 Gbit/s OFDM optical wireless communication link over the underwater channel( 2020) João Henrique Araújo ; Luís Manuel Pessoa ; Henrique Salgado ; Pereira,F ; Joana Santos Tavares ; Kraemer,R ; 7658 ; 4760 ; 296 ; 5686An OFDM transmission system is reported based on a directly modulated blue LASER diode, for high bit rate under-water optical communication applications. The 256 subcarriers 16-QAM signal is transmitted over a total distance of 2.4 m underwater with an EVM lower than -28.5 dB for a 250 MHz bandwidth and -16.5 dB for a 2 GHz bandwidth, the BER being lower than the forward error corrector limit. At the maximum bandwidth of 2 GHz a transmission rate of 5.36 Gbit/s is achieved. © 2020 IEEE.
ItemExperimental Evaluation of Resonant Tunnelling Diode Oscillators Employing Advanced Modulation Formats( 2018) Henrique Salgado ; Joana Santos Tavares ; Luís Manuel Pessoa ; 5686 ; 296 ; 4760The performance of Resonant Tunnelling Diode (RTD) oscillators with an optical window is evaluated experimentally, in the transmission of advanced modulation formats using electrical and optical modulation, for the first time. Additionally, the impact of phase noise in the transmission performance is also assessed. © 2018 IEEE.
