Wideband Adaptive Prediction

View page
US Patent:
46548637, Mar 31, 1987
Filed:
May 23, 1985
Appl. No.:
6/737330
Inventors:
William R. Belfield - Tinton Falls NJ
Raymond S. Medaugh - Middletown NJ
Assignee:
AT&T Bell Laboratories - Murray Hill NJ
International Classification:
H04B 1406
US Classification:
375 27
Abstract:
Superior performance, better tracking, and stability of an adaptive predictor are realized by employing a so-called high order (eighth) prediction filter and by updating the filter coefficients in accordance with an algorithm based on the sign of a reconstructed signal sample (s. sub. q (k)) multiplied by a quantized version (e. sub. q (k)) of a differential error signal normalized by an expected magnitude of the reconstructed signal sample.

Method And Apparatus For Measuring The Noise Content Of Transmitted Speech

View page
US Patent:
59501545, Sep 7, 1999
Filed:
Jul 15, 1996
Appl. No.:
8/680760
Inventors:
Raymond Stephen Medaugh - Wharton NJ
Ronald Shaya - Morristown NJ
Assignee:
AT&T Corp. - Middletown NJ
International Classification:
G10L 302
G10L 900
US Classification:
704226
Abstract:
A noise filter technique estimates noise in speech that has been processed by Call Multiplication Equipment. The received signal has speech frames and interspersed fill-noise frames inserted at a satellite signal receiving station. The filtering technique removes the fill-noise from the signal. The remaining speech frames are analyzed such that the speech frames having the lowest power values are used to create a histogram of power/frequency. This histogram contains information from which the noise-in-speech power spectrum is derived.

Digital Code Converter

US Patent:
44752130, Oct 2, 1984
Filed:
Dec 27, 1982
Appl. No.:
6/453502
Inventors:
Raymond S. Medaugh - Middletown NJ
Assignee:
AT&T Bell Laboratories - Murray Hill NJ
International Classification:
H04L 2516
US Classification:
375 27
Abstract:
Accumulation of distortion possibly resulting from multiple digital code conversions is prevented by including in an ADPCM-to-PCM decoder (100, FIG. 1 or 600, FIG. 6) an arrangement (119, FIG. 1 or 601, FIG. 6) for making a trial transmission of the resulting PCM sample (. PSI. (k)) to obtain (via 209, FIG. 2) a composite noise value (. alpha. (k)) for the PCM sample (. PSI. (k)). The composite noise value includes noise components resulting from both quantizing the code word and truncating digital signals used in the decoder and subsequent coder. The composite noise value is evaluated (via 211) to determine whether adjustment of the PCM sample value (. PSI. (k)) is necessary. In one embodiment (FIG. 1, 100), a reconstructed linear version (Y. sub. r (k)) of the PCM sample is adjusted (via 216, 218, 220 or 221) when the composite noise value (. alpha.
