Homework Help: Complex integral

  1. Jun 6, 2010 #1
    1. The problem statement, all variables and given/known data
    I'm studying the non-linear effect of power amplifier on multicarrier siganl. I have come across an complex integral which is given below, but not able to figure out how to solve it analytically.


    2. Relevant equations

    [tex]I=\frac{A^2}{2\sigma_x^4}\int_{0}^{\infty}\frac{r^3}{r^2+A^2}\exp(\frac{j\pi}{3}\frac{r^2}{r^2+A^2}-\frac{r^2}{2\sigma_x^2})dr[/tex]

    Please help me solve this integral.
