摘要：
In this paper, we study the multi-rate transmission for MC-DS-CDMA systems based on the concepts of multi-code (MC) access and variable-spreading-length (VSL) code access. The general system model is derived for multi-rate MC-DS-CDMA systems of either multi-rate access and multiuser detections (MUD) are proposed thereof. We analyze the characteristics of multi-rate MC-DS-CDMA signals and investigate the behaviors of MUDs. Compared studies and simulations among the proposed MUDs and access methods suggest VSL-code access with the proposed LMMSE detection to multi-rate MC-DS-CDMA systems, especially for transceiving high-rate users.
