hi guys, i'm new in matlab central so hello to everyone. i've a problem in my program. the program it's about propagation in an optical fiber of a signal qpsk modulated. I can't post the functions here because it would be too long. if someone wants to help please contact me and i will give him all the program folder. i'm so close to the solution but i can't understand where i've to correct something. i think it's right but it doesn't seem. i hope someone will answer me. thanks everybody.
No products are associated with this question.
Use .* instead of * when you desire element-by-element multiplication. For example,
x = 1:3 y = 4:6 x.*y
You probably need
ep = exp(-a.*dz/2).*ifft((exp(-i.*dz.*d/2)).*fip);
In particular I suspect the dot missing between the exp() term and the ifft() term is the key.
