Speech recognition with amplitude and frequency modulations [PDF]
Proceedings of the National Academy of Sciences, 2005 Amplitude modulation (AM) and frequency modulation (FM) are commonly used in communication, but their relative contributions to speech recognition have not been fully explored. To bridge this gap, we derived slowly varying AM and FM from speech sounds and conducted listening tests using stimuli with different modulations in normal-hearing and cochlear ...

AUTOMATIC RECOGNITION OF BOTH INTER AND INTRA CLASSES OF DIGITAL MODULATED SIGNALS USING ARTIFICIAL NEURAL NETWORK [PDF]
Journal of Engineering Science and Technology, 2014 In radio communication systems, signal modulation format recognition is a significant characteristic used in radio signal monitoring and identification. Over the past few decades, modulation formats have become increasingly complex, which has led to the ...

A first investigation into the effectiveness of Tactons [PDF]
, 2005 This paper reports two experiments relating to the design of Tactons (or tactile icons). The first experiment investigated perception of vibro-tactile "roughness" (created using amplitude modulated sinusoids), and the results indicated that roughness ...

Synthetic speech detection and audio steganography in VoIP scenarios [PDF]
, 2016 The distinction between synthetic and human voice uses the techniques of the current biometric voice recognition systems, which prevent that a person’s voice, no matter if with good or bad intentions, can be confused with someone else’s.

Research on modulation recognition with ensemble learning [PDF]
EURASIP Journal on Wireless Communications and Networking, 2017 Abstract Modulation scheme recognition occupies a crucial position in the civil and military application. In this paper, we present boosting algorithm as an ensemble frame to achieve a higher accuracy than a single classifier. To evaluate the effect of boosting algorithm, eight common communication signals are yet to be identified.

Recognition of narrowband rausing autoregressive models and pattern comparison approach
Journal of Telecommunications and Information Technology, 2002 This paper presents an improved spectral recognition method for digitally modulated radio signals. It is based on a signal autoregressive (AR) model. Model poles are used as signal features for neural network based on recognition process.

A Method of Noise Reduction for Radio Communication Signal Based on RaGAN
Sensors, 2023 Radio signals are polluted by noise in the process of channel transmission, which will lead to signal distortion. Noise reduction of radio signals is an effective means to eliminate the impact of noise.
