Kalman Filter with an Accelerometer Hi, I wanted to estimate the position of something using data collected from an accelerometer. Now, I know this is a noisy process, so I wanted to use some filtering technique to get accurate position and velocity from just accelerometer readings. I was told that the Kalman Filter would do just the thing. I first d... 21 Mar 2010 17:19

lms-dfe implementation Hi experts, I am a usual ng lurker but now it is time to make my first question, as I am stuck on a lms-dfe implementation issue. I use the textbook equations (implemented in Scilab) to estimate, via LMS, the filters coefficients. I do a classical LMS to estimate the fwd filter coeffs, still being in training m... 19 Mar 2010 14:20
Details on ESPS' get_f0 function work Hi! I am experimenting with pitch analysis with the help of ESPS. Can anyone give a few hints? I cannot find in manuals here http://www.ee.uwa.edu.au/~roberto/research/speech/local/entropic/ESPSDoc/manpages/indexes/index.html about in what amplitude range a processing signal should be? Should it be [-1,+1]... 19 Mar 2010 08:09
FFT Radix 3 I have been trying to code a normal C program for a radix 3 fft problem. My program works for 3,6,9,27 points but conks off for the 81 point fft onwards. I would like to know if there is a mistake in my program or is it because VC can't support such intensive calculations ;P. Well I really don't know how to go ahead.I ... 19 Mar 2010 17:46
Capacity for QAM Guys, I need a clarification on shannon capacity equation for QAM systems with coding. Lets assume M-QAM with code rate R Let m = log2(M) My goal is to find at what SNR (Eb/No) we achieve capacity with the shannon equation. C= Wlog2(1+SNR). I am a little confused. can someone please explain with a... 21 Mar 2010 23:13
