Detection of the fundamental frequency in noisy environment for speech enhancement of a hearing aid

Proceedings of the 1999 IEEE International Conference on Control Applications (Cat. No.99CH36328), 1999

This paper describes a method for noise-proof detection of the fundamental frequency of the voice in a noisy environment. Noise reduction techniques have been required in the development of a hearing aid, because noise makes intelligibility of hearing awfully inferior. In various methods of noise reduction, the fundamental frequency is often a significant parameter, but it is difficult to extract ...

IEEE Transactions on Automatic Control, 1980

The dual feedback path automatic gain control system ideally has closed-loop frequency response independent of input level if certain component parameters are matched. The method of harmonic balance is used to analyze mismatch error, which is shown to be easily manageable using typically available components. Due to the complexity of the general problem, a symbolic/algebraic computer system was used.

  • Detection of the fundamental frequency in noisy environment for speech enhancement of a hearing aid

    This paper describes a method for noise-proof detection of the fundamental frequency of the voice in a noisy environment. Noise reduction techniques have been required in the development of a hearing aid, because noise makes intelligibility of hearing awfully inferior. In various methods of noise reduction, the fundamental frequency is often a significant parameter, but it is difficult to extract the frequency from the noisy voice. In order to utilize a comb filter method for noise reduction, a new method of detecting the fundamental frequency is developed by using the property of continuity in the fundamental frequency and the power spectrum envelope (PSE) of the human voice. The continuity of the PSE is utilized for determining the most reliable frequency. The gross pitch error (GPE) is reduced by the determination. Besides the frequency used for the comb filter is obtained from a linear predicting frequency and the latest fundamental frequency from the noisy voice, so as to suppress fluctuation of the frequency that degrades filtered voice. The procedure improves a fine pitch error (FPE) within 5%. The results of the evaluation showed that the present method proved to be superior to the traditional cepstrum method in the GPE and the FPE. We conclude that the proposed frequency detection method is available for noise reduction in the comb filter method.

  • A Sequential Detection System for the Processing of Radar Returns

    This paper describes a system which permits a substantial reduction in the amount of equipment required for the detection of narrow-band radar returns which may fall into any part of a wide, noisy Doppler band. The system utilizes a two-step process; the first providing a coarse, high false-alarm indication of range and Doppler, and the second providing high-quality detection and parameter estimation. The basic principles are discussed, followed by a description of an experimental prototype system. Experimental results are presented.

  • A precise 90/spl deg/ quadrature OTA-C VCO between 50-130 MHz

    We present a VLSI continuous time sinusoidal OTA-C quadrature oscillator fabricated in a standard double-poly 0.8 /spl mu/m CMOS process. The oscillator is tunable in the frequency range from 50-130 MHz. A symmetric topology assures that the two phases produced by the oscillator present an extremely low phase difference error (less than 2/spl deg/ over the whole frequency range). A novel current mode amplitude control scheme is developed that allows for very small amplitudes. Experimental results are provided.

  • Another Source of VOR Omni Error

    In the vicinity of reflecting objects, a VOR receiver picks up both the direct and reflected signals. This summation adds both amplitude and phase modulation to the signal that were not present at the transmitter. The error due to this phase modulation is fairly evident since the desired directional information is transmitted as a relative phase. What is not so evident is the fact that the amplitude modulation can also produce a phase error. This happens when asymmetrical filters are used to process the amplitude-modulated signal. The asymmetrical filter converts some of the amplitude-modulated sidebands into phase modulation which is recorded as a direct phase error.

  • A 400MHz 10Mbps D-BPSK receiver with a reference-less dynamic phase-to-amplitude demodulation technique

    A 400MHz 10Mbps differential BPSK (D-BPSK) receiver (RX) is presented. This RX adopts a proposed reference-less dynamic phase-to-amplitude demodulation scheme, which converts signal phase transition to distinct amplitude variation. The proposed RX can support a data rate up to 10Mbps. It achieves -63dBm sensitivity at 0.1% BER and draws 1.77mW in 0.18μm CMOS.

  • Direct Evaluation of Radar Detection Probabilities

    A simple and effective procedure for evaluating detectionperformances in radar and sonar detection problems is derived forboth fixed-threshold and adaptive- threshold detection. Using theprocedure, the cumulative probabilities of the test statistic can bedirectly evaluated from the moment generating functions bycalculating residues. The exact formulae for computing the detectionperformances for the chi-square family of fluctuating targets withan integer fluctuation parameter are given in a finite sum formwithout any special functions for both fixed threshold and cellaverageconstant false-alarm rate detection by using the methoddeveloped here.
