While fewer and fewer people are listening to FM radio today, it was hot stuff amid its widespread rollout during the late 1930s and early 40s. Short for frequency modulation, FM’s appeal compared to ...
Radio spectrum is pricey. Operators drop billions at auction to lock down licensed frequency bands, and every single frequency counts. Dynamic Spectrum Sharing (DSS) was built to address exactly this, ...
Abstract: Short time Fourier transform (STFT) is an excellent two-dimensional time-frequency analysis tool that can effectively analyze the time-frequency characteristics of signals. However, it is ...
ABSTRACT: This paper presents a comparative study of four Sinusoidal Pulse Width Modulation (SPWM) strategies Phase Disposition (PD-PWM), Phase Opposition Disposition (POD-PWM), Alternate Phase ...

Abstract: In this study we introduce Logarithmic Frequency Shift Keying (Log-FSK), a novel frequency modulation for over-the-air computation (AirComp). Log-FSK leverages non-linear signal processing ...
Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...
