Abstract

Abstract: Based on the Okumura-Hata propagation model, we analyze theoretically and effect of MAI on the WCDMA property, and educe the relation between MAI and coverage and capacity. The result of simulation indicates that, when MAI rises by 1dB, the WCDMA coverage area will reduce by 12%, and that the MAI's increase also reduces capacity. In a word, this effect will be different if the NodeB antenna's height, NodeB transmit signal power or cell coverage radius is different.

Key words: MAI, WCDMA, capacity
