Abstract

Quality-of-service (QoS) support by power distribution and rate allocation for heterogeneous services in multicode code division multiple access (MC-CDMA) systems is studied. Power distribution among all participating connections achieves high resource utilization subject to satisfaction of SINR specifications for the allocated transmission rates. Rate allocation ensures that the required delay/jitter and loss requirements for different connections, while efficiently utilizing the system resources by statistically multiplexing the random and bursty traffic streams. The resultant call level grade of service (GOS) performance, including resource utilization and connection blocking probability (CBP), is derived. Numerical results are given to demonstrate the GOS performance
