- 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.

Sorts input matrix of data so that each column is re-ordered by user-specified criteria. Options are (1) sort data by signal width (2) sort data by energy localization (3) sort data by dissimilarity of data to a normal probability distribution. The default option is to return all 3 options, as vectors of indices so that W(:,Iw), for example, gives the data ordered by signal width.

- Speech Coding Using Sub-Bands
- License: Freeware
- Price: 0.00

Sub band processing is based on splitting the frequency range into M segments (subbands),which together encompass the entire range. Each subband is processed independently, as called for by the specific application. The subbands are recombined after processing, to form an output signal whose bandwidth occupies the entire frequency range.
