Homework Statement
Im having some trouble setting up this problem.
##x(t)## is a polar signal with random binary data. The data is independent from bit to bit. ##P(0)=P(1)=\frac{1}{2}## Assume ##a_n=+/-1##.
The fundamental pulse shape is attached.
I need to find the Power spectral density of x(t)
Homework Equations
$$S_y(f)=\frac{|P(f)^2|}{Tb}$$
The Attempt at a Solution
Ok so as i mentioned I am having trouble setting up this problem. From the fundamental pulse shape I can determine that my pulse width is ##\frac{T_b}{3}##
Im not sure how to treat the ##P(0)=P(1)=\frac{1}{2}##.
I think I need to find my ##x(t)## and calculate the Fourier transform of it ##x(f)## or ##p(f)## in my formula above. Then square it and divide by the pulse width. If this is correct. What my ##x(t)##? How do I go about finding it from the information given.
Any ideas?
