MATLAB is a software environment and programming language with over 1,000,000 users and is used to generate arbitrary and standard waveforms, configure and control instruments, build automated test applications, and analyze and visualize data from other instruments. MATLAB only supports... Platforms: Matlab

Current direct sequence code division multiple access (DS-CDMA) system suffer from Multiple access interference (MAI) and Inter symbol interference (ISI) due to the frequency selective channel. This interference can be avoided by use of Adaptive Beamforming. There are two different minimum... Platforms: Matlab

This entry provides functions and examples allowing you to create Simulink.TsArray and Simulink.TimeSeries objects from a script or the MATLAB command line. A Simulink.TsArray object can be used as input data for a bus signal input in Simulink.Note: These functions contain **UNDOCUMENTED**... Platforms: Matlab

random_band is the main program and it outputs a test signal which has a constant level. The instanatenous frequency varies randomly within the specified Nth octave band range.The program outputs three plots: time record of the instantaneous frequency, time record of the instantaneous level, and... Platforms: Matlab

This program operates as a signal spectrum analyzer and a distortion meter at the same time. It can accept any numerical data representing few cycles of a signal. The data do not need to be equally separated. At least ten data points per cycle are needed. Higher number of data points will of... Platforms: Matlab

A signal object (an object of class "signal") is a set of data in an one dimensional array, combined with information about its sample rate, starting time and other useful infos. A number of methods makes it easy to generate and modify signals."signal" is used and tested for considerable time in... Platforms: Matlab

We present some basic programs written for the MATLAB environment for the analysis of optical and acoustic data and for signal processing. These programs exploit novel concept derived from a theoretical physics approach. These programs can be easily customized by the expert user, but they... Platforms: Matlab

Frequency response signal analyzer for linear and non-linear control loops and dynamic systems. Simulink model. Sine sweep based similar to dynamic signal analyzers for physical systems. User specifies: freq limits, freq decrement, averages, phase criteria for moving to next frequency, start... Platforms: Matlab

This function NLMF performs Non-Local Means noise filtering of 1D signal, 2D grey/color or 3D image data. The function is partly c-coded for cpu efficient filtering. Suitable for almost every image data type such as MRI, CT and normal photos.Warning !, Image filtering removes noise, but important... Platforms: Matlab
