摘要：
Power control is an effective technique to reduce cochannel interference and increase capacity for cellular radio systems. The purpose of forward-link power control in a CDMA system is to reduce the amount of interference in neighbouring cells by reducing the total amount of power transmitted. In an underlaying two-tier system, microcell's capacity is limited by the forward link due to the interference from macrocell's basestation. Therefore, forward-link power control is required to enhance system capacity and reduce outage probability. In this paper, we study the effect of imperfect forward-link power control due to the limitation of power transmitted by basestation. Performance measures including capacity, outage probability and service hole area are analysed. Copyright (C) 2002 John Wiley Sons, Ltd.
