Hi all,
I'm trying to calculate symbol error probability of variant of pulse position modulation considering only AWGN channel. The decoder is maximum likelihood so the implementation of the detector is by using vector correlators.
$$
\arg \max_{x} <y,x>.
$$
Attached is the waveforms vector...
Hi ,
I have the book called "optical wireless communication:system and channel modeling with matlab" and i'm currently learning PPM modulation.
i've come to the part on performance under AWGN channel where the author explained about the error probability with soft decision and came to the...
Hello all,
i have frustrating task in my lab...
i have to generate a code in MATLAB that will get the focal length and the object distance from the lens, i.e image (1000X1000 pixels).
transfer it through the lens and, for the output it should be the result of it: inverse,magnified/shrinked...
Hi all
this is an idea that I have for my thesis
I have Gaussian pulse and i am deciding to divide it to wavelength slots like this :
the slots are defined like that-> each slot will have the same energy -> so the each interval will be different in wavelengths.
i(receiver) have to know the...
sorry , but i had to mention that it isn't the same event , because every detector working on different channel/frequency/wavelength and each one of them carry information.
Hi all ,
Having communication system that bit error rate at every detector is 10^-9
if the system have two same detectors what is the total error probability ?
Psuccess(i)= successive probability at 'i' detector.
BER(i)= bit error rate at 'i' detector.
is it...
Hi all
I have simple assignment in MATLAB, where i need to take the Fourier transform of an very short Gaussian pulse and plot the intensity Vs frequency.
knowing the 1. lineshape of gaussian 2. Fourier of Gaussian is Gaussian,
I think all i need is to calculate with MATLAB the fft for this...
Hi all
I am doing for my final year project a simulation with OFDM system.
i needed a fast function to calculate the LLR, so
I found this code on mathworks,

Creating Jakes Doppler filter
Hello
I want to create Jakes Doppler filter in matlab "the classical model"
using this power spectrum:
with firpm function,
anyone know how ?
To be honest that's the only line I can say the I understood (as I can sum up that back in the old days u didn't have matlab :) ), sorry...
So if you familiar with Matlab you probably mean that I'll use berfit command , but which parameters ? should I use ?
As for the number of bits that I...
