This paper presents experimental results of the key technologies of the Wideband DS-CDMA (W-CDMA) physical layer employing inter-cell asynchronous operation with a three-step fast cell-search algorithm, pilot symbol-assisted coherent links, signal-to-interference plus background noise power ratio (SIR)-based transmit power control (TPC), site diversity, and transmit diversity. Link capacity enhancing techniques such as using an interference canceller and adaptive antenna array diversity are presented with experimental results. The laboratory and field experiments show the superiority of the W-CDMA physical layer techniques and the potential of the interference canceller (IC) and adaptive antenna array diversity (AAAD) to reduce the MS transmit power in the reverse link and other user interference with large transmit power in the forward link.
