INTRACELL C/I BALANCING TECHNIQUES FOR UPLINKS OF A MULTI-CELL CELLULAR CDMA SYSTEM

摘要: 本文采用兩種區(qū)內(nèi)C/I平衡技術(shù)來(lái)控制多區(qū)蜂窩CDMA系統(tǒng)上行鏈路中移動(dòng)臺(tái)的發(fā)射功率,用以補(bǔ)償陰影和路徑損失的影響;采用與傳統(tǒng)不同的小區(qū)平均中斷概率(Outage probability)來(lái)評(píng)價(jià)它們的性能。

Abstract: Two intracell C/I balancing techniques are presented for controlling mobiles transmitter powers on the uplinks of a multi-cell cellular CDMA (Code Division Multiple Access) system in order to compensate the combined effects of shadowing and path loss, with their performance being evaluated in terms of cell-averaged outage probability which is different from the traditional index. -
