Abstract

This paper compares a wireless telecommunication system employing W-CDMA transmissions from both terminal-to-base and base-to-terminal, with a novel system which employs spread-TDMA transmission from terminal-to-base and W-CDMA transmission from base to-terminal, thereby providing high quality performance in both directions. The systems are compared on the basis of capacity in a multipath, multiple cell, environment and on the basis of complexity. The spread spectrum receivers employed in both systems employ matched filters, which permit connectionless as well as connection-based packet switched communications at data rates up to 12 Mb/s, for multimedia or LAN applications, as well as voice communication
