Hi, everyone.
Recently I've been reading this paper where the receiver has two differential output for I and Q channel respectively. The analysis simply assumes an output of I+jQ, but this is a complex signal. How do you measure the noise figure? Is there any instrument for analyzing complex signals?
Thanks![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
