Walsh-Hadamard 코드를 이용한 하향링크 MC(Multi-Carrier)-CDMA 시스템의 PAPR(Peak to Average Power Ratio) 특성을 조사하여 최적의 코드 할당 방식을 개발한다. MC-CDMA 시스템의 PAPR은 코드 조합의 선택에 크게 의존한다는 것을 알 수 있습니다. 이러한 사실을 바탕으로 활성 사용자 수에 따라 PAPR을 최소화하는 할당 방법을 개발합니다. 또한, 최소에 가까운 PAPR을 위해 효율적인 차선 코드 조합 검색 방식도 제안된다.

Abstract: We develop an optimum code allocation scheme by investigating the peak to average power ratio (PAPR) characteristic of a down-link multi-carrier (MC)-CDMA system using Walsh-Hadamard code. It is shown that PAPR of a MC-CDMA system is highly dependent upon the selection of code combination. Based on this fact, we develop the allocation method which minimizes PAPR according to the number of active users. In addition, an efficient suboptimum code combination search scheme is also proposed for near minimum PAPR.
