Akses Berbilang Bahagian Kod Jujukan Langsung (DS-CDMA) ialah salah satu calon yang paling berkemungkinan untuk sistem komunikasi mudah alih generasi ke-3. Sebaliknya, rangkaian yang menyokong pemindahan data bersepadu dan menyediakan kualiti perkhidmatan (QoS) yang boleh diramal kepada aplikasi tersebut merupakan isu yang menarik. Kertas kerja ini mencadangkan beberapa skim berdasarkan peraturan majoriti yang berkaitan dengan tempahan sumber untuk menyiasat prestasi sistem selular CDMA. Kawalan kemasukan adalah berdasarkan kapasiti sisa dan nisbah isyarat-ke-bunyi (SNR) yang diperlukan untuk trafik multimedia termasuk suara, data dan video. Prestasi sistem diterokai dengan keuntungan penyebaran berubah-ubah dan sistem CDMA berbilang kod di bawah skim yang dicadangkan. Selain itu, beberapa parameter sistem termasuk kebarangkalian lepas tangan (seumur hidup dalam sel) dan beban trafik disiasat untuk mengkaji kesan kepada prestasi sistem. Keputusan menunjukkan pertukaran antara kebarangkalian menyekat panggilan baharu dan kebarangkalian menghentikan panggilan lepas tangan dalam situasi yang pelbagai. Walau bagaimanapun, ia tidak cekap di bawah tempahan sumber kerana kapasiti yang tidak digunakan. Dalam kertas kerja ini, kami juga mencadangkan skim peminjaman sumber untuk meningkatkan prestasi sistem. Keputusan simulasi menunjukkan bahawa algoritma cadangan kami benar-benar meningkatkan prestasi sistem dalam sistem selular CDMA multimedia dengan tempahan sumber.

Abstract: The Direct-Sequence Code Division Multiple Access (DS-CDMA) is one of the most likely candidates for the 3rd generation mobile communication systems. On the other hand, a network supporting integrated data transfer and providing predictable qualities of service (QoS) to such application is an attractive issue. This paper proposes several schemes based on the majority rule concerned with resource reservation to investigate the performance of a CDMA cellular system. The admission control is based on the residue capacity and required signal-to-noise ratio (SNR) for multimedia traffic including voice, data and video. The system performance is explored with variable spreading gain and multi-code CDMA systems under the proposed schemes. Moreover, several system parameters including the handoff probability (lifetime in a cell) and the traffic load are investigated to study the impact to system performance. The results show the trade-off between the blocking probability of new calls and dropping probability of handoff calls under diversified situations. However, it is inefficient under resource reservation due to unused capacity. In this paper, we also propose a resource-borrowing scheme to improve system performance. Simulation results show that our proposed algorithm really improves the system performance in a multimedia CDMA cellular system with resource reservation.
