Symbol signal-to-noise ratio loss in square-wave subcarrier downconversion [PDF]

open access: yes
This article presents the simulated results of the signal-to-noise ratio (SNR) loss in the process of a square-wave subcarrier down conversion. In a previous article, the SNR degradation was evaluated at the output of the down converter based on the ...
