Listing of Communication in Scripts

This file improves on the functionality of interp1 and allows the resampling of more complex data. Measurements can be taken completely arbitrarilly and need not be unique. Target uses are for data which is sampled against a signal that may contain noise or where there may be several measurements at each given point.

PHP Call Center is a web-based application used to keep track of a company's incoming phone calls. It is unlike other call loggers in that it is not based on "tickets" as those systems are often confusing and cumbersome to use..

Here I don't provide any code (yet), but I'd like to hear your voice of feedback about what you fellow Matlab developers think. The more you express enthusiasm, the sooner there will be actual code available for download. The more you criticize and the more constructive suggestions and comments you post the better it will be.

This function computes the Modified Hausdorff Distance (MHD) which is proven to function better than the directed HD as per Dubuisson et al. in the following work: M. P. Dubuisson and A. K. Jain. A Modified Hausdorff distance for object matching. In ICPR94, pages A:566-568, Jerusalem, Israel, 1994.

EXtrinsic Information Transfer (EXIT) charts are useful for characterizing the convergence properties and the performance of turbo receivers. Turbo receivers are generally constructed from two or more Soft Input Soft Output (SISO) modules. By simulating a single SISO module, the transfer characteristic of the SISO module can be obtained using the EXIT class.

This method, known as swept-sine, log-chirp, swept-tone, or sine sweep uses an increasing frequency sinusoid to stimulate an acoustic device under test. The response is processed to compress the response to an impulse response. This method is robust against noise, time variance, and weak nonlinearities.

The inputs are the imf's amplitud and the imfs instantaneous frequency. The outputs are the Marginal Hilbert Spectrum (mhs) amplitude vector and a frequency vector corresponding to the amplitude vector. In order to obtain a more interpretable graph the instantaneous frequency vector can be quantized grouping values of frequency Which are very close.

ScaleTime - fast linear matrix interpolation I have recorded timeseries of e.g. size [100'000 x 10] and cut out chunks of about 100 frames according to some events and normalize them to exactly 100 frames. For this task, the direct approach with Matlab's INTERP1 works, but it is slow: interp1(1:size(Y, 1), Y, Ti, '*linear') Cutting Y to blocks of 1000 frames at first accelerates the computing, but encreases the complexity.

A number of rules of thumb exist for the advantages of non-coherent averaging, I wanted to see, in a fairly practical way, what the advantage really was. This turned out to be more complex than I thought, because you have to identify and implement separate parts to the equations for the output noise.

According to shannon theory it is possible to reconstruct a band limited signal from its Fourier components provided it is sampled sufficiently...just to demonstrate this, posting a small example based on that.

You can use 4 types of filters: - Butterworth - Chebyshev 1 - Chebyshev 2 - Elliptic You can use them as: - Lowpass - Highpass - Bandpass - Stopband Showing theirs features in frequency, phase and the z plane. After the desing phase you can apply the designed filter in real time to incoming audio signal from the microphone.

As I could find no built-in function nor reliable contribution to achieve that, I had no choice but to write my own, leveraging the GregorianCalendar Java class. Usage is quite simple: targetDST = TimezoneConvert( dn, fromTimezone, toTimezone ) The datenum dn corresponds to the datetime you want to convert.

The WCDMA Physical Layer Demo consists of an end-to-end (transmitter-to-receiver) simulation of the Frequency Division Duplex (FDD) Downlink physical layer for several Dedicated Channels (DCH) as specified by the 3GPP standard (Release 99). The current ZIP file includes three different models: channel coding, spreading and modulation and the complete physical layer.
