I have a signal that has complex normal distribution with mean 0 and variance of 1. I want to quantize it with a uniform quantizer to 512 levels. Does someone has any idea how to quantize such a complex signal in matlab? I would appreciate any input.

Normal distribution has an infinite tail. If you quantize it with a fixed number of uniform levels then you cannot cover the entire range. Unless you want to quantize by CDF?
Does the signal have a constant magnitude? Could you show us the generating function?

+/- 3.097269078198785 would leave 1/512'th of the data outside the range.
round(s / 3.097269078198785 * 256)/256
