Abstract

In CDMA cellular systems, multicode transmission is an effective way of accommodating multimedia traffic having various transmission rates. We proposed a common searcher configuration at a base station to successfully handle multicode signals. The number of searchers needed in a base station can be reduced because a multicode signal needs only one searcher. We evaluated the call blocking probability and communications quality when the number of searchers is restricted
