How to find all roots of this high order polynomial equation? [3 articles]

Hi all, I need to find all real $u$'s, such that $$\sum_{i=1}^{n}{\left(\frac{w_{i}}{u-e_{i}}\right)^{2}}=1$$ where $$\sum_{i=1}^{n}{w_{i}^2}=1$$ and w_{i}'s and e_{i}'s are given. My ques...

Iterative Match Filterings [61 articles]

Instead of just taking the convolution of a signal with the reference or kernel once and then taking the square root in the frequency domain, why not match filter with the reference again and again ...

About Reed-Solomon [14 articles]

Hi all, just out of curiosity, I was digging into the RS codes, mainly for RAID-6 purposes. So, I was wondering about the possibility of increasing the parity of such RAIDs. Looking around ...

A Few FFTs Short of MPC [32 articles]

What has been and is being called "matched filtering" might better be called "a few steps short of complete match filtering" [which has the often desirable effect of _adding_ in some low pass filter...

Complex AM demodulation- simple question [4 articles]

To demodulate AM, I use the formula am = sqrt(I*I + Q*Q) I am mixing an AM IF signal to baseband, i.e. carrier plus 2 sidebands. My test signal is modulated at 800Hz. When I look at the demodula...

What's under the hood?? [10 articles]

Hey, I just watched a demo of this amp profiler...I guess it's a kind of system identification algorithm running under the hood? Any guesses as to what type of algorithm is used to identify the a...

basic questions on jpeg compression [18 articles]

Folks, I have few basic questions on related to compression used in JPEG. 1. Is the DCT applied over Y, CB and CR separately? 2. Is there a specific reason why DCT is chosen over DFT? 3. Ca...
