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:

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

With the division of spectrum resources, a huge rock in the road of TD-LTE commercialization was moved. At the recently held "TD-LTE technology and spectrum Seminar", China's 2.6GHz spectrum planning scheme was announced,-2690hz of the 2.6GHz band all divided into TDD spectrum. The determination of

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

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
