COMMUNICATION METHOD AND APPARATUS USING HYBRID MODULATION SCHEME IN COMMUNICATION SYSTEM

Provided are a communication method and apparatus using a hybrid modulation scheme in a communication system. The communication node uses a hybrid modulation scheme in the communication system and includes a processor, a first light-emitting diode (LED) array configured to transmit a first signal by blinking a first LED set according to control of the processor, a second LED array configured to transmit a second signal by blinking a second LED set according to control of the processor, and a memory configured to store one or more instructions executed by the processor. Therefore, performance of the communication system can be improved.
