- 論文の詳細を見る
This work focuses on the problem of efficient assignment of the orthogonal-variable-spreading-factor (OVSF) codes for multimedia communications in W-CDMA systems. Due to the problem of code blocking, the OVSF-code assignment algorithms proposed so far cannot efficiently serve the high-raterequests. Although Minn and Siu proposed the algorithm to eliminate the code blocking, the system implemented with such the algorithm has the lower number of simultaneous voice conversations than the one of the system with the code blocking problem. To efficiently provide the services for all supported rates, we propose an OVSF-code assignment scheme called the region division assignment (RDA). The performance of the proposed RDA scheme is evaluated by simulation.
