Abstract

It is very important to reduce the PAPR(Peak to Average Power Ratio) in the OFDM(Orthogonal Frequency Division Multiplexing) communication system. The proposed method in this paper is an effective PAPR reduction method using the Golay complementary codes without my side information. There are some PAPR reduction methods with the complementary code pairs or sequences. They are usually a type of the forward ewer correction codes so that they produce more redundancies and lower down the code rate. Because of this, the information rate may be cut down or more bandwidth must be required. In this paper, we propose a PAPR reduction method that uses the multi-phase complementary code f3r converting the 4-QAM into 16-QAM constellation. It does not change the code rate and does not require the side information.

PAPR(Peak to Average Power Ratio)를 줄이는 것은 OFDM(Orthogonal Frequency Division Multiplexing) 통신 시스템에서 매우 중요하다. 본 방법은 Golay상보 부호에 의한 PAPR 감소 기법의 한 가지 방법으로서,부가 신호를 사용하지 않으면서 효과적으로 PAPR을 감소시킬 수 있는 방법이다. 기존의 상보 부호에 의한 PAPR의 감소기법은 오류 정정 부호를 사용하거나 부가 신호를 사용 데이터 전송율이 감소하게 된다 있다. 본 논문에서는 단지 복수위상 상보부호를 이용하여 4-QAM의 성상도를 16-QAM의 형태로 변환하고 부가신호의 추가 및 부호율 증가에 영향을 주지 않는 PAPR감소 기법을 제안한다.
