• One way of accommodating multimedia traffic having various transmission rates is to use multicode transmission in CDMA cellular systems. A multicode user, however, corresponds to locally concentrated single-code users, and the simultaneous transmission of multiple signals causes non-uniform traffic on cellular systems. We evaluate the performance of multicode transmission in CDMA systems in terms of call blocking and communications quality. We also estimate the number of receivers and searchers needed in a base station. Our previously proposed dynamic cell configuration (DCC) scheme reduces the adverse effects of non-uniform traffic in CDMA systems. In the present study, we found that the use of DCC for voice/data integrated traffic using multicode transmission reduces call blocking and improves communications quality for both voice and data users.
