MULTICARRIER PERSONAL ACCESS COMMUNICATION SYSTEM

摘要

A highly modular PACS-based system that combines the advantages of Orthogonal Frequency Division Multiplexing (OFDM) and Personal Access Communication System (PACS) with Time Division Multiple Access (TDMA) technology. The system is arranged to support high-speed (higher than the 32 kbps of PACS) wireless access services to fixed and mobile users. For example, nomin al user data rates of 32-to-356 kbps are attainable, and even the higher speed of 76 8 kbps is possible for short ranges.
