TL;DR: In this article, a method for encoding a channel using a parallel convolutional encoder is described, which includes the steps of a first step for performing an encoding operation at the time when a data is inputted into a frame input data register, and a second step for storing the thusly generated code symbol into an interleaver RAM which is alternately selected by the frame unit.

TL;DR: The provision of reliable modeling of the human body as a passage of the electric signal delivery based on the impulse response measurement is addressed through the proposal of a measurement setup and signal processing techniques applicable to wearable devices for healthcare and biosignal acquisition.

TL;DR: This work proposes a new pitch detection algorithm for noisy speech using a noise whitening technique on the background noise and obtains successful results.

TL;DR: In this paper, the authors proposed a method to receive a speech signal, perform a recognition weighting process on it, synthesize a synthetic speech signal and calculate an autocorrelation of the synthesized speech signal whose delay is a predetermined value, to divide the square of the former by the latter, to calculate a pitch lag and a pitch filter coefficient by calculating only the part of a positive peak with skipping over the negative peak.

TL;DR: In this article, a flexible bit rate code vector generation method was proposed by using an algebraic codebook search process in a wideband AMR-WB vocoder, where the preprocess divides a sub-frame by tracks and decides a pulse position having a maximum value in each track.
