I'm totally new to FT:s (obviosly) and don't know much of the math involved.
I have a real input signal (Fs=44100) which I've transformed to a
complex and I was hoping to be able to regene...

What, no comments on the recent Google Image Recognition
flap? You know, which identified a pair of black hominids as gorillas -
It's funny, but even funnier, and astonishing, is that Google

I'm using hann windowing for PAPR reduction. After windowing the peak
value and average value of signal reduces and overall PAPR increases
after dividing peak value with average value.what should i d...

please help me to interpret some strange(?) behaviour of Huffmann coding
and entropy. Let me explain it at an example:
Consider a source emitting four symbols x1-x4 with probabilities

I would like to simulate IEEE802.11a WLAN over a Rayleigh multipath
channel using Matlab and I'm dealing with the function
"h=rayleighchan(ts,fd,tau,pdb). I'm really confusing about the sample

I have implemented an almost "universal" (read: compatible with most other
decoders output) Reed-Solomon codec. I feel like I have a good intuitive
grasp on the whole codec, except for on...

Continuing an old post regarding Hamming window overlaps:
The first answer gives:
"a 50% overlap would give a sum of 1.08".
If I wis...

I have two signals and I want to know which signal is more periodic than
other. My approach:
1. Make both signals zero mean.
2. Take FFT of both signals.
3. Take sum of squared value...

hi all ,
I simulated OQpsk modulated data which has 4 samples per symbol (bas=
e band). I also simulated the squaring and differentiating based Timing err=
or detector .Now i want to know h...

Trying to implement kelly lochbaum for vocal tract I have a problem to
represent closed mouth: 0 area gives a k=1, (total reflection of presure
wave seems ok to me) but 1+k=2 means pressure is not 0 i...
