- SNR for Coherent and Non-Coherent Filtering
- License: Freeware
- Price: 0.00

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.

- Extended Euclidean Algorithm for polynomials over GF(2^m)
- License: Freeware
- Price: 0.00

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).

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.

- License: Freeware

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.
