A codec is a device which helps to encode or decode digital data signals, it encodes a data
stream or encrypted form and a decoder operates a reverse process of encoder. This …

Mobile telephony is omnipresent in modern society. Currently there are more ac-tive mobile
phone subscriptions than inhabitants on the planet. One technological building block …

Speech processing algorithms usually segment signals into finite-length blocks or windows,
since block operations are generally more efficient in terms of both bitrate and computational …

The performance of speech communication applications in the field of mobile devices is
often hampered by background noises and distortions. Therefore, noise attenuation …

In this work, we propose a novel approach to speech coding by rewriting the nonlinear
analysis-by-synthesis linear prediction scheme as a convex problem. This allows for …

It is shown an encoder for encoding an audio signal with reduced background noise using
linear predictive coding. The encoder includes a background noise estimator configured to …
