Apparatus and method for data transmission by constellation combination in a communication system

摘要

Disclosed are an apparatus and a method for efficiently transmitting data by constellation combination in a communication system. The method includes encoding and interleaving transmission data according to a predetermined encoding scheme, and dividing an interleaved signal into at least one signal interval corresponding to at least one modulation scheme; and transmitting data obtained by modulating at least one divided signal interval according to a modulation scheme corresponding to the divided signal interval, the data satisfying a predetermined data rate setup in a system by applying a preset modulation scheme to each divided signal interval.
