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.

Contains two functions. The one function computes the greatest common divisor (gcd) of two polynomials a(x) and b(x) over GF(2^m). The other function performs the extended Euclidean algorithm where two polynomials u(x) and v(x) is calculated in addition to the gcd of a(x) and b(x) such that gcd = u(x)a(x) + v(x)b(x).

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.

This software has been realized at the Technology Lab, Department of Cognitive and Neural Systems, Boston University - http://techlab.bu.edu. The main author of the software is Praveen Pilly ( http://techlab.bu.edu/members/advait/ ). How does the brain make perceptual decisions? Speed and accuracy of saccadic decisions regarding motion direction depend on the inherent ambiguity in the motion stimulus and correlate with the temporal dynamics of firing rates in parietal and frontal cortical neurons of macaque monkeys.

This package contains a set of functions for inferiential statistics using resampling methods. Data are organized into arrays so multiple tests can be run at once (up to one million test per second). The package supports bootstrap, permutation and parametric statistics using paired or unpaired t-test, or repeated measure ANOVA (one way and two ways).

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.

The task of this work is to extract a signal radiating from a specific direction in the presence of a jamming signal being transmitted at same frequency. There are four cases in the first case transmitter and jammer are in different directions and are at equal range from receiver but the jammer is switched off that is there is no interference signal.

Samplify for Matlab allows sampled data users (those capturing real-world samples from A/D converters, or sending samples to D/A converters) to compress these samples in one of three compression modes: a) SignalZIP (TM) lossless mode, b) Samplify fixed-rate mode (users specify the desired compression ratio) c) Samplify fixed-quality mode (users specify the desired dynamic range) Samplify for Matlab demonstrates the achievable rate-distortion tradeoffs (higher bit rates have lower distortion) of the Samplify compression algorithm.
