Re: qam matlab projects

hi, i'm working on 8psk modulation for GSM ,,,,,
can you please give me some 8psk codes

Hello Everyone. I need to generate a binary data stream of duration Ts. After, I need to collect the even bits to create the in phase stream and stretch these slot in duration 2Ts.

I need to do the same for the odd bits.

Can you please help me

Hi all

Does any one have a QAM or QPSK PassBand mod/demod .m files?

I tryed to program it myself but when I multiply the quadrature component by sin I get values that very close to 0, ( I do not have a problem when I choose low Carrier Freq)

it's looks like this : imag(Y)*A*sin(2*pi*Fc*t);
while Y is the quadrature component and Fc is 10000Hz.

When I multiplying the inphase component by cos I get the correct signal


I would appreciate if anyone can explain to me whas wrong in my code.. and also If anyone can send me to my email or post here .m file of QAM/QPSK PassBand Transiever.

I was actualy asking for .m file, not simulink files
I need this work for my final project, and it has to me matlab .m files

Thanks for you'r efforts anyway.

If anyone can kindly help me with my problem it will be great.
