송신기 전력 제어는 셀룰러 DS/CDMA 시스템의 성능을 향상시키는 효과적인 방식입니다. 역방향 링크에서는 전력 제어 성능을 향상시키기 위해 수신 신호 전력 추정을 보조하기 위해 파일럿 심볼이 사용됩니다. 본 논문에서는 레일리 플랫 페이딩이 존재하는 상황에서 전력 제어 역방향 링크 CDMA 시스템의 성능을 평가하기 위한 모델을 제안합니다. 이 모델을 사용하면 파일럿 심볼 수, 전력 제어 업데이트 주파수, 최대 허용 전송 전력과 같은 설계 매개변수를 분석할 수 있습니다. 분석 결과, 송신기 전력 제어를 사용할 경우 셀룰러 통신의 일반적인 정규화된 도플러 주파수에 대해 시스템 용량을 40% 이상 늘릴 수 있는 것으로 나타났습니다.

Abstract: Transmitter power control is an effective scheme to improve the performance of cellular DS/CDMA systems. In the reverse link, pilot symbols are used to assist the estimation of received signal power in order to improve the performance of power control. In this paper, we propose a model for the evaluation of the performance of a power-controlled reverse link CDMA system in the presence of Rayleigh flat fading. The model allows analysis of design parameters such as the number of pilot symbols, the power control updating frequency and the maximum allowable transmitted power. Analysis result shows that when transmitter power control is used, system capacity can be increased by more than 40% for typical normalised Doppler frequency in cellular communications.
