Plotting AWGN in baseband binary transmission
4 visualizzazioni (ultimi 30 giorni)
How do I plot this?
S0(t)= sqrt(2*E/T) sin(pi*t/T)
S1(t)= sqrt(2*E/T) sin(2*pi*t/T)
where T is the period and E is normalized.
Can someone teach me how to plot this because I dont know how to plot E and T.

Your question is not clear. In the equation you have mentioned there is no mention of AWGN. It is not clear what you want to plot. The expression you have mentioned , it seems that it is of a signal of Symbol period 'T' for binary trnasmission. Multiplication by Sqrt[2*E/T) is done so as to ensure that the energy of the signal is 1. This is also a kind of normalization. For transmitting 1 and 0 usually the amplitudes are inverted. So Amplitude will be like Sqrt[2*E/T) for 1 and negetive of that for 0. So I dont know what you want to plot. I am below mentioning a plot for the BPSK transmission of a sequence of bits
x = [0,1,0,0,0,1,1,1]; % Bits to be transmitted
T= 1 ; % Symbol Period
len = length(0:0.001:1);
for i = 1:length(x)
s(1,p:p+len-1) = (-1)^(1+x(i)) * sqrt(2*0.1/1) * sin(2*pi*(0:0.001:1)/T);
For details clarify your question and reply back. Hope this helps
