Label: style blog HTTP Io color ar OS sp The first part of this article first explains the AR spectrum, but it does not give too much details. The second part introduces several common speech features, some of which have been used in previous blog posts, such as the zero-crossing rate. The third part provides the actual operation process and recognition results. The goal of this paper is to extract the characteristics of the voice signals collected b

Rate Matching: Bit Rate Selection Channel environment: AWGN Signal-to-Noise Ratio: SNR Bit Rate R: 1/2, 1/3, 1/4, 1/8 MATALB simulation architecture: Source bit + convolution code/Turbo (1/3) + Rate Matching (different R) + PSK modulation + AWGN + PSK demodulation + decoding rat

The effect of the three-day music spectrum: Includes five classes: MusicControl class, which is used to control music, including the control of music loading and playback. ID3Control class, used to extract information related to music files, display various information cyclically, and display garbled characters in extracted Chinese. Here, you can use a function to correct the information: Function EncodeUtf8 (str: String): String { Var oriByteArr:

convert it: Parameters: They represent the strength (and phase) of the harmonic components of signals at various frequencies ). By bringing the f (x) signal into the above formula, we can calculate the harmonic at each frequency. (The complete discussion of Fourier transform involves the complex space. The above shows a more intuitive series form) Spectrum (frequency spectrum) Through Fou

DfT again understand 2015.12.18 Before learning "signal and system", for the use of FFT () function analysis of discrete, continuous time signal spectrum out of the result has been a smattering of knowledge, this semester learned "digital signal processing", learning the discrete Fourier transform (DFT), the previous written procedures to do further understanding. Before this, the CTFs, Dtfs, Ctft, DTFT formulas are listed to facilitate understanding:

This article mainly introduces the installation of the basic environment of Spectrum chain development in Linux environment, including Ubuntu and CentOS environment. It also provides a way to create a docker image. It is recommended to install in a Docker environment to avoid installation success due to environmental differences and to deploy quickly. Installation System environment (the following environment has been tested) Ubuntu:ubuntu 16.04

The five parallel crosslines used to record notes are called the five-line spectrum. The five lines of the Five-line spectrum are computed from the bottom up.If a piece of music is written on several lines of music, these lines of music will also be linked by a hyphen.The concatenation number consists of two parts: the starting line (the vertical line of the Five-line s
