Baru-baru ini, skim capaian berbilang pembahagian kod dengan dupleks pembahagian masa (CDMA/TDD) telah menarik perhatian sebagai cara untuk merealisasikan sistem komunikasi multimedia tanpa wayar yang cekap. Dalam kertas kerja ini, kami mencadangkan dua algoritma peruntukan slot masa untuk sistem CDMA/TDD untuk menampung trafik multimedia dengan cekap. Dengan mengandaikan persekitaran sel berbilang praktikal dan model perkhidmatan multimedia yang terdiri daripada beberapa jenis perkhidmatan suis litar dan suis paket dengan kualiti perkhidmatan (QoSs) yang berbeza, kami menilai purata kelewatan (purata masa dari penjanaan panggilan ke penugasan saluran) bagi sistem CDMA/TDD dengan algoritma yang dicadangkan, dan bandingkan prestasi dengan prestasi CDMA dengan dupleks pembahagian frekuensi (CDMA/FDD) dan capaian berbilang pembahagian masa dengan sistem TDD (TDMA/TDD). Keputusan simulasi komputer kami menunjukkan bahawa sistem CDMA/TDD dengan salah satu algoritma yang dicadangkan, yang boleh mengelakkan gangguan secara berkesan di kalangan pengguna dengan QoS berbeza, boleh meningkatkan prestasi kelewatan purata berbanding dengan sistem lain.

Abstract: Recently, code division multiple access scheme with time division duplex (CDMA/TDD) has drawn considerable attention as means to realize efficient wireless multimedia communications system. In this paper, we propose two time slot allocation algorithms for CDMA/TDD systems to efficiently accommodate multimedia traffic. Assuming a practical multiple cell environment and a multimedia service model which consists of several kinds of circuit-switched and packet-switched services with different quality of services (QoSs), we evaluate the average delay (average time from call generation to channel assignment) of the CDMA/TDD system with the proposed algorithms, and compare the performance with that of CDMA with frequency division duplex (CDMA/FDD) and time division multiple access with TDD (TDMA/TDD) systems. Our computer simulation results show that the CDMA/TDD system with one of the proposed algorithms, which can effectively avoid interference among users with different QoSs, can improve the average delay performance as compared with the other systems.
