Abstract
A receiving device, includes a memory; and a processor coupled to the memory and configured to: when amplifying a multi-valued signal of a multi-valued modulation technique according to a control signal, acquire a first multi-valued signal before amplifying the multi-valued signal and a second multi-valued signal after amplifying the multi-valued signal, detect a first peak voltage of the first multi-valued signal, detect a second peak voltage of the second multi-valued signal, and control the control signal based on the first peak voltage and the second peak voltage such that a maximum amplitude of the second multi-valued signal and linearity of the second multi-valued signal are maintained.
