[Discuss-gnuradio] question and a couple of interesting links

[Toby Oliver]

Hi,

Firstly a quick question, can anyone give me some pointers on the how to 
calculate the optimal parameters for the least mean squared decision 
feedback equalizer in Gnuradio, or is this a case of going a reading up 
in something like Proakis?

Secondly I came across a couple of interesting projects which might be 
useful to some people here (apologies if you are aware of them already):
- streamit (http://cag.csail.mit.edu/streamit/) a  programming language 
and a compilation infrastructure from MIT which is basically concerned 
with optimising streaming of data. It does a number of things, including 
algebraic simplification of stateless filters (e.g., FIR, FFT, DCT) and 
stateful filters (e.g., IIR, feedback loops).
- spuc (http://spuc.sourceforge.net/) a GPL C++ signal processing library

Regards,
Toby
