다중 반송파 변조의 문제점 중 하나는 HPA(High Power Amplifier)와 같이 채널의 비선형성으로 인한 비선형 왜곡입니다. 이 문제는 다중 반송파 SS(Spread Spectrum) 시스템에서도 마찬가지입니다. 본 논문에서는 다중 반송파 M-ary/SS 시스템을 위한 상호 변조 보상 기법을 제안한다. 심각한 상호 변조 왜곡 발생을 피하기 위해 병렬로 전송되는 시퀀스를 제어하는 두 가지 방법을 제안합니다. 하나는 약간의 중복이 필요한 "패키지 순서 선택" 방법입니다. 또 다른 방법은 오류 정정 코드를 기반으로 하며 오류 정정을 위한 중복성 외에 추가 주파수나 전력이 필요하지 않습니다. 제안한 기법의 타당성을 컴퓨터 시뮬레이션을 통해 확인하고, AWGN(Additive White Gaussian Noise) 채널에서의 BER(Bit Error Rate) 성능을 제시한다.

Abstract: One of the problems in multi-carrier modulation is nonlinear distortion due to nonlinearity of channels, such as in HPA (High Power Amplifier). This problem is also true of multi-carrier SS (Spread Spectrum) systems. In this paper, an inter-modulation compensation scheme for multi-carrier M-ary/SS system is proposed. We propose two methods to control the sequences transmitted in parallel to avoid the occurrence of severe inter-modulation distortion. One is the "package sequence selection" method, which requires slight redundancy. The other method is based on error correction code, which requires no additional frequency or power except the redundancy for error correction. We confirm the validity of our proposed scheme by computer simulation, and the BER (Bit Error Rate) performance in an AWGN (Additive White Gaussian Noise) channel is presented.
