AM-FM energy detection and separation in noise using multiband energy operators
This paper develops a multiband or wavelet approach for capturing the AM-FM components of modulated signals immersed in noise. The technique utilizes the recently-popularized nonlinear energy operator Y (s) = (S)'-ss to isolate the AM-FM energy, and an energy separation algorithm (ESA) to extract the instantaneous amplitudes and frequencies. It is demonstrated that the performance of the energy...
متن کاملSpeech event detection using multiband modulation energy
The need for efficient, sophisticated features for speech event detection is inherent in state of the art processing, enhancement and recognition systems. We explore ideas and techniques from non-linear speech modeling and analysis, like modulations and multiband filtering and propose new energy and spectral content features derived through filtering in multiple frequency bands and tracking dom...
متن کاملCombating nonlinear telephone channel-noise using the multiband AM-FM model
This study presents a novel technique to enhance telephone speech signals. This technique is based on the Amplitude and Frequency Modulation (AM-FM) model, which represents the speech signal as the sum of N successive AM-FM signals. Based on a leastmean-square error criterion, each AM-FM signal is modified using an iterative algorithm in order to compensate for the deformation of the signal cau...

دراین پروژه به بررسی مدل سازی خشک کردن مواد غذایی با استفاده از هوای خشک در خشک کن آزمایشگاهی نوع سینی دار پرداخته شده است. برای آنالیز انتقال رطوبت در طی خشک شدن به طریق جابجایی، یک مدل لایه نازک برای انتقال رطوبت، مبتنی بر معادله نفوذ فیک در نظر گفته شده است که شامل انتقال همزمان جرم و انرژی بین فاز جامد و گاز می باشد. پروفایل دما و رطوبت برای سه نوع ماده غذایی شامل سیب زمینی، سیب و موز در طی...
15 صفحه اولMulticomponent AM-FM demodulation via periodicity-based algebraic separation and energy-based demodulation
Previously investigated multicomponent AM–FM demodulation techniques either assume that the individual component signals are spectrally isolated from each other or that the components can be isolated by linear time-invariant filtering techniques and, consequently, break down in the case where the components overlap spectrally or when one of the components is stronger than the other. In this pap...
