Abstract :
A high data rate proposal for a 1.25 MHz DS-CDMA system, called 1XTREME (1xEV-DV), is capable of supporting peak rates of up to 4.8 Mbps and average data rates of approximately 1 Mbps. It is a true evolution of the cdma-2000 CDMA system, being fully backward compatible and therefore able to support both voice and data users on the same carrier. A new forward shared channel (F-SHCH) with an associated forward control channel carries the high-speed packet data. The associated forward control channel structure is shown to offer a 30% increase in the active users on the system over a typical structure. Furthermore, additional channels are added in the reverse link to support the various throughput-enhancing features of 1XTREME. In this paper, the details of the air-interface are presented along with the description of each channel. Also, the simulated performance of the F-SCH and the forward control channels are presented
