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

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...

I just finished the reading of An introduction to different rounding
algorithms, http://www.eetimes.com/document.asp?doc_id=1274485. I must
admit I never pay much attention on the trick of the quan...

I am facing some issue with my echo cancellation module.
I am having a correlator and an adaptive filter modules. My correlator
will detect presence of echo in the DTMF tones and will activate the
