Abstract: Blind modulation identification (BMI) of 6G aeronautical multibeam satellite (MBS) systems is prominently challenging due to the intricacy of shadowed-Rician (SR) fading, limited channel ...
Abstract: This study proposes an orthogonal frequency division multiplexing (OFDM) based scheme to achieve interference-free backscatter communications (BC) in a symbiotic radio system. In this scheme ...
A low pulse on this pin (below 1/3 of VCC) sets the internal flip-flop and makes the output go HIGH. When the voltage on this pin reaches 2/3 of VCC, it resets the flip-flop, and the output goes LOW.
