Ted Lyngmo - 2015-07-07 17:16:00
Hi! 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...FFTw - Manually regenerating the original signal

theresajc - 2015-07-07 09:23:00
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...hann window for PAPR reduction

Entropy before and after Huffmann coding vs. channel capacity [10 articles]

qfran - 2015-07-06 12:19:00
Dear all, 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 P(x1...Entropy before and after Huffmann coding vs. channel capacity

Hi, 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 ...IEEE802.11a Matlab Simulation

Reed-Solomon FEC necessary to have the same characteristic for symbols and words? [5 articles]
0

lrq3000 - 2015-07-02 12:58:00
Hi there, 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...Reed-Solomon FEC necessary to have the same characteristic for symbols and words?

mavavilj - 2015-07-01 16:22:00
Continuing an old post regarding Hamming window overlaps: http://www.dsprelated.com/showthread/comp.dsp/105321-1.php The first answer gives: "a 50% overlap would give a sum of 1.08". If I wis...hamming window overlap #2

sia4uin - 2015-07-01 16:16:00
Hello All 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...Find periodicity of a signal

sonoro - 2015-06-30 07:28:00
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...kelly lochbaum closed mouth
