In case anyone has been dying to attend one of my talks (or send an
associate), I'm now hooked up with a company that presents seminars.
Basically, they do all the work that I absolutely dreaded ...

I'm learning about GNU Radio and software radios in general. However, I
just have very rudimentary knowledge about DSP (did a really basic college
course) and the mathematics related to it. I picked u...

I suspect he's describing a non-problem, or a problem in pretty
extreme corner cases.

I have an IQ signal that I mix with a complex oscillator to bring signals
down to 0 hz. I now need to do a lowpass filter on the signal to remove
all other signals before demodulating the signal...

There's a statement in Smiths The Scientist and Engineer's Guide to
Digital Signal Processing about the effect of fft length on noise. In
arguing the virtues of averaging multiple short fft's instead ...

Could you please help me to evaluate the advantages and disadvantages of Joint Kalman Filter and Dual Kalman Filter, and a comparison of the two methods.
Thank you very much,
Here's something you may not know. Suppose you want to expand in a power series a polynomial. Let's take a simple one
Then if you write a lower triangular toeplitz matrix

First post to this group!
I have 3D accelerometer signals which are obviously noisy. I want to use
Kalman filter to remove the noise.
I can also use a moving average filter and it w...

I'm looking for some guidance on how random vibration control is
performed. I've read that the reference signal is a PSD (power spectral
density) rather than a time domain signal. And that the feedb...

For an experiment i have a simple application that takes a quadrature
signal from a radio and then does the following:
Complex FFT -> Inverse FFT -> Cartesian to Polar -> audio out
If I tune...
