Abstract
The design concept of wideband multi-rate DS-CDMA (W-CDMA) that can support various services with different data rates and also flexible system deployment is presented. It is characterized by asynchronous cell site operation with fast cell search algorithm, pilot symbol assisted coherent reverse/forward links, and forward links that use tree-structured orthogonal multi-spreading factor (SF) codes. Adaptive antenna array diversity and interference canceller are designed to further enhance the transmission quality and increase the link capacity. Field experiments including 2 Mbps transmission are also presented.
