1. A pulse-amplitude modulation (PAM) transmitter comprising:
a transceiver; and
at least one processor connected to the transceiver and configured to:
identify, from among symbols included in an input signal, a symbol that exceeds a specified transition level;
when the symbol exceeding the transition level is identified, obtain a frame buffer comprising at least one bit among bits constituting the identified symbol;
encode input data by inverting at least one bit among the bits constituting the identified symbol; and
transmit the frame buffer and the encoded input data.
