Orthogonal Subcarrier Generation
Change the frequency of three subcarriers and the symbol duration to see the effect on orthogonality in the frequency domain
Subcarrier 1
Subcarrier 2
Subcarrier 3
Time domain — subcarrier 1
x₁(t) = cos(2π·200·t) · rect(t/T)
Time domain — subcarrier 2
x₂(t) = cos(2π·400·t) · rect(t/T)
Time domain — subcarrier 3
x₃(t) = cos(2π·600·t) · rect(t/T)

Analytical Fourier transform
Xᵢ(f) = T/2 · [sinc(T(f−fᵢ)) + sinc(T(f+fᵢ))]
