DSP: Noise Averaging WCDMA Example

The following example show noise averaging affects for a WCDMA signal. Coherent averages were taken of a WCDMA signal with additive noise k=.1.

The first plot shows a pure WCDMA modulated signal with additive noise.

Next, the signal is plotted with three (3) noise averages:

Finally, ten (10) averages are simulated:

The plot below shows a zoomed in area of the shoulder.
