Hello all,
Kindly, can any one help with matlab code for Baseband signal generation or even bandpass. nd tells which modulations are suitable for them.

thanx in advance
 

what do you mean by baseband signal?
 

mathuranathan said:
Baseband signal can be generated in number of ways . Refer a standard communication text book to represent band pass signal interms of baseband signal.

One simple way to generate a arbitrary baseband signal is to generate a PRBS pattern and pass it through a low pass filter with appropriate cut off frequency.

thanx Mathuranathan,
here is a quote from one has posted it in this site:

what type of signal you want to generate ?? and for which application it is??

The most common one is:
Fs=1e3; %Sampling Frequency
t=(0:Fs)'/Fs; % Time vector
f=30; %Frequency
x=sin(2*pi*f*t); % Baseband signal
plot(t,x);grid on;

HTH,
Ashwini
