IR-UWB Radar-Based Contactless Silent Speech Recognition with Attention-Enhanced Temporal Convolutional Networks
Sunghwa Lee, Jaewon Yu
Silent speech recognition (SSR) is a technology that recognizes speech content from non-acoustic speech-related biosignals. This paper utilizes an attention-enhanced temporal convo…
Toward High Accuracy DME for Alternative Aircraft Positioning: SFOL Pulse Transmission in High-Power DME
Jongmin Park, Seowoo Park, Sunghwa Lee +2
The Stretched-FrOnt-Leg (SFOL) pulse is an advanced distance measuring equipment (DME) pulse that offers superior ranging accuracy compared to conventional Gaussian pulses. Success…
IR-UWB Radar-Based Contactless Silent Speech Recognition of Vowels, Consonants, Words, and Phrases
Sunghwa Lee, Younghoon Shin, Myungjong Kim +1
Several sensing techniques have been proposed for silent speech recognition (SSR); however, many of these methods require invasive processes or sensor attachment to the skin using…
Movement Detection of Tongue and Related Body Parts Using IR-UWB Radar
Sunghwa Lee, Younghoon Shin
Because an impulse radio ultra-wideband (IR-UWB) radar can detect targets with high accuracy, work through occluding materials, and operate without contact, it is an attractive har…
SFOL DME Pulse Shaping Through Digital Predistortion for High-Accuracy DME
Sunghwa Lee, Euiho Kim, Jiwon Seo
The Stretched-FrOnt-Leg (SFOL) pulse is a high-accuracy distance measuring equipment (DME) pulse developed to support alternative positioning and navigation for aircraft during glo…
