Performance of Medium Access and Radio Link Control Algorithms for Mobile Multimedia CDMA Systems

초록

In this paper, we introduces a mobile multimedia CDMA system configuring multiple transmission links between a user and radio ports. We propose a centralized reservation access control scheme with transmission scheduling and allocation algorithm supporting diverse multimedia traffics. We also propose two types of transmission allocation algorithms: local information algorithm and global information algorithm. The transmission allocation algorithms allocate a set of ports configuring multiple radio links and transmission slot/power to each of scheduled transmission requests. We evaluate the performance of the proposed CDMA system and control algorithms, comparing a distributed random access CDMA system and a dynamic TDMA system.
