Abstract: The type of services and the manner with which multiple access is performed have a tremendous impact on the system capacity. The capacity region for video services in the uplink of a round-robin carrier-hopping multi-rate Multi-Carrier (MC) DS-CDMA cellular system is derived by formulating and analyzing the outage probabilities in terms of bit error rate specifications. The subcarriers of the MC-DS-CDMA system are dynamically allocated to evenly distribute their usage. Three management schemes are used to perform subcarrier allocation: complete sharing (CS), dynamic complete partitioning (DCP) and dynamic complete group partitioning (DCGP). The analytical framework is formulated for the general case in which different traffic classes have different spreading gains in each of the subcarriers. Numerical results show that the capacity of DCGP is larger than that of CS or DCP. © 2007 IEEE.
