KISS FFT converts a time-domain signal (a series of samples from a microphone, ADC, accelerometer, etc.) into the frequency domain, revealing which frequencies are present and how strong each one is.

Abstract: Radio frequency fingerprint identification (RFFI) is an emerging method for authenticating Internet of Things (IoT) devices. RFFI exploits the intrinsic and unique hardware imperfections for ...

Abstract: This letter proposes a novel rhombic dual-polarized and dual-band patch antenna array design for 5G millimeter-wave (mmWave) mobile devices as an antenna-in-package (AiP). The proposed ...
