Does any one have QAM,QPSK,BPSK, etc...Matlab codes

qpsk matlab code

hello,
Hey friends.. I need Matlab code for digital modulation techniques... like ASK, PSK, BPSK, DPSK, QAM, QPSK, etc... If you have that, Please post that...



Advance tnxs to you

qpsk with matlab code

see the attached

by the way
there are many others on matlab file center

matlab qam

Did you have Matlab 7.5 version, there are also some default examples for modulation techniques and even IEEE 802.16 d 2004 WiMAX simulink is exist. (go->help->just type qam or qpsk..)

Enjoy!

qpsk matlab

Hi mashhur
not only matlab 7.5 have these examples
the other versions includes many examples

thank you for your reply

bpsk vs qam

Please can I find some source code about ADSL modem I need to have some source code please.

Thanks a lot friends

64 qam program in matlab

i need the matlab to generate 64 qam and also to convert 64 qam to 16qam

 

[Aya2002]

mat lab code for qam

Hi freind,
you can not convert between them as i know but you can demodulate at 64 and then modulate at 16.

thanks alot
if you have any thing new in matlab as a simple projects or aplication plese send me at aarrwnas@yahoo.com

matlab program for generating qpsk

hi
i want matlab code with comparison of Systems 8-PSK and 8-FSK it is easy my friends?

 

[sathish2610]

qpsk project

Hi AYa2002,

thank u for ur reply..

i am doing the project based on repeater...

while i am working,i need the program to convert 16 qam to 4qam...

as u said it can be converted through 16 qam to baseband and then to 4qam..

can u send the matlab code for the above conversation AYA
so that i can continue in my project based on repeater.....

matlab code bpsk

my freind if you know how to do the psk modulation using modem object in matlab and the modulate method. you can see the program that i posted in the following link and you can modify it to your requist.



Thanks

matlab code for qam

any one has a code matlan in QPSK modulation and demodulation? if you have file *.m, that is better....could you send for me via quanghaidv04@yahoo.com

coding of qam in matlab

Hi Aya,

Do you have Spatial multiplexing matlab code and Space time block coding matlab code? I really need it. I could find some STBC code on google but it's not complete, not working. Please provide me if you have.

Also do you know anything about precoding?

matlab source code for qpsk modulation

I am so sorry my friend, I do not have it
