ask matlab code

len = 10000; % Number of symbols
M = 16; % Size of alphabet
msg = randint(len,1,M); % Original signal
% Modulate using PAM,
txpam = pammod(msg,M);
% Perturb the phase of the modulated signal.
phasenoise = randn(len,1)*.015;
rxpam = txpam.*exp(j*2*pi*phasenoise);
% Create a scatter plot of the received signal.
scatterplot(rxpam); title('Noisy PAM Scatter Plot');
% Demodulate the received signal.
recovpam = pamdemod(rxpam,M);
% Compute number of symbol errors.
numerrs_pam = symerr(msg,recovpam);

ask matlab program

Hi everyone

I am a serious newbie in this modulation techniques I have been reading up and still do not understand.

if i need to design a QASK modulation scheme in MATLAB of the following specifications, how do i do this?

Bandwidth: 200 kHz
Centre frequency: 1.420 MHz
Signal Power available: 1 mW
Noise Power Spectral density: 1.0 10 9 W/Hz

channel considered ideal and the noise additive white Gaussian. It is to be
represented in MATLAB using a sampling frequency of = 10 MHz

free to choose
- the symbol set size, M.
- the pulse shaping, g(t).
- the symbol rate, R.

thank you so much for ur help. u can also direct ur advice to cool_boyz28@hotmail.com

In simulink you can find the ASK modulator as a PAM modulator.

I DONT think you can ever find a Matlab code for cell phone jammers. You may get a simulation

I'd say Sklar covers most topics, but is just a bit complex.

There is another book by Glover and Grant, you can have a look at its contents
