**16QAM modulation MATLAB code**Hi,
I am facing a problem in generating a waterfall graph with the BER i calculate for each SNR value by using 16 QAM modulation. Instead of getting a waterfall graph, I get a straight line. Anyone can helps me?
It's urgent.
Hope to hear from you soon.
Thanks.
P.S : Please pm me so that we can have further discussion on my problem.

**frequency modulation simulation in matlab**i an doing an electronics project and would like to use matlab to
simulate what my hard ware is doing
basically what im doing is frequency modulating a sound wave onto the
mains 220v 50hz signal and transmitting it then the other end
recieving the 220v 50 hz signal and demodulating it to extract the
sound wave any tips on where i should look or some sample code would
be great i have little to know background to matlab so any help would
be greatly appreciated
cheers

**Frequency Modulation using Matlab**HEllo All,
I am having one querry regarding MATLAB.
What I would be doing is that I will give the signal from a microphone
and I have to use MATLAB so that the signal gets frequency modulated
and then I will be taking the output from the headphone jack and mix it
with a carrier frequency [Local Oscillator] and send it to the spectrum
analyzer.I am doing a project named (Software Radio) where you have to
do the signal modulation using Software
So could some one help with the code I have written below
it is giving the error.
??? Error using ==> +
Matrix dimensions must agree..
