Abstract
“Software Radio” has drawn much attention as a means to support multimedia services in wireless communications. Software radio gives us a possibility that we can adaptively change not only modulation/demodulation and channel coding schemes but also multiple access scheme. Here, one question naturally arises; “In software radio, can just a single access scheme such as TDMA or CDMA effectively support multimedia services?” or “If we can select even an access scheme, is it more beneficial?” In this paper, we discuss the traffic performance enhancement when we have a freedom in selecting an appropriate access scheme out of TDMA and CDMA. With typical multimedia service model supposed to be provided in third or later generation mobile communications systems, we evaluate the traffic performance in terms of average delay time by computer simulation.
