title: How to generate a complex gaussian white noise signal in python(or numpy/scipy)?
body: <p>I am doing some works about DSP(digital signal process), and there need to generate a discrete complex white gaussian noise signal. I know I can use <code>numpy.random.normal(0, 1, n)</code> to generate the discrete sequence, but it is in real number field. It is easy to simulate with Matlab, but I wander how to replace matlab code with python?</p>
