PilotPattern.show() interpolates plot for high number of subcarriers #1003
Description
Hi,
this is just a very minor issue but I think it can be fixed quickly: when using a high number of subcarriers, the PilotPattern.show() interpolates the pilot pattern image.
The plt.imshow() uses for the ResourceGrid.show() uses the keyword argument interpolation="nearest" which is missing in the corresponding PilotPattern.show() imshow(), creating a slightly strange figure since it does not match the discrete structure.
