Abstract

In this paper, the reverse link performance of imperfect power controlled cdma2000 cellular system that using array at a base station is analyzed, when MCGM beamforming algorithm and power control error is considered in shadowing. The blocking probability of the cdma2000 cellular system based on array parameters, E$\_$b//N$\_$0/ and interference statistics is calculated, and then the system capacity is calculated at a specific blocking probability. When the blocking probability is set 1 %, PCE(power control error) is 2 dB, M=2, 4, 8, 10, the capacity of cdma2000 is increased 2.3 ∼ 2.5 times higher than IS-95.

본 논문은 기지국 배열 안테나를 이용하여 전파음영 환경 하에서 MCGM 알고리즘과 전력제어 오차에 따른 cdma2000 셀룰러 시스템의 역방향 링크에 대한 성능을 분석한다. 블록킹 확률을 배열 파라미터와 $E_{b/}$ $N_{0}$ 및 간섭통계를 이용하여 유도하고 특정한 블록킹 확률에서의 시스템 용량을 계산한다. 1 %의 블록킹 확률, 전력제어 오차 2 dB, 배열 안테나 소자 수 M=2, 4, 8, 12에서 cdma2000 시스템과 IS-95 시스템의 사용자 수는 각각 21, 40, 75, 110명과 9, 17, 30, 44명으로 나타나, cdma2000 시스템이 IS-95 시스템에 비해 2.3~2.5배의 용량 증가를 보였다.다.다.
