다중 코드 광대역 CDMA 시스템을 위한 일정한 진폭 전송 방식이 제안되었습니다. 멀티코드 광대역 CDMA 시스템에서는 멀티코드 신호가 구성 코드 채널 신호의 합이기 때문에 진폭 변동이 큽니다. 이러한 큰 진폭 변동은 큰 비선형 왜곡을 가져오며, 이를 설명하지 못할 경우 비트 오류율(BER) 성능을 크게 저하시킬 수 있습니다. 월시 코드와 패리티 생성기를 사용하여 달성되는 일정한 진폭 전송은 큰 진폭 변동에 대처하고 PAPR(피크 대 평균 전력비)을 줄이기 위해 제안되었습니다. 제안하는 방식은 다른 정진폭 전송 방식과 달리 중복 코드 채널을 사용하지 않는다. 컴퓨터 시뮬레이션 결과는 제안한 방식이 BER 성능을 크게 향상시키며, 제안한 방식이 HPA(High Power Amplifier)의 비선형 왜곡에 매우 효과적이라는 것을 보여줍니다.

Abstract: A constant amplitude transmission scheme for multicode wideband CDMA systems is proposed. Multicode wideband CDMA systems result in large amplitude fluctuation because the multicode signal is the sum of constituent code channel signals. This large amplitude fluctuation brings out large non-linear distortion and then, if unaccounted, can significantly degrade the bit error rate (BER) performance. Constant amplitude transmission, achieved by using a Walsh code and parity generator, is proposed to combat the large amplitude fluctuation and reduce the peak-to-average power ratio (PAPR). Unlike other constant amplitude transmission scheme, the proposed scheme does not use a redundant code channel. Computer simulation results show that the proposed scheme improves BER performance significantly and that the proposed scheme is extremely effective to the non-linear distortion of high power amplifier (HPA).
