摘要：
An apparatus and a method for operating a transmitter supporting constellation rearrangement for 256-Quadrature Amplitude Modulation (QAM) in a broadband wireless access system are provided. The method include generating complex symbols according to a first version of a constellation mapping rule, transmitting an initial transmit packet comprising the complex symbols, and when retransmitting the initial transmit packet, generating complex symbols according to a second first version of a constellation mapping rule.
