Abstract

This article describes a wideband-spread code-division multiple access (W-CDMA) system for high-capacity and high-quality personal radio communication. This system has been authorized as an EIA/TIA Interim Standard IS-665, T1P1 Trial Use Standard J-STD-015, and ITU-R Recommendation M.1073. The system uses wideband spreading to accomplish good interference immunity, high-quality speech, and high-peed data transmission. The system uses coherent detection (CD) and an interference canceller system(ICS) to enhance the capacity. CD and ICS use continuous pilot signals in the forward/reverse links to estimate the propagation path parameters. PN and Hadamard sequences are used as the spreading code for minimal mutual interference between traffic and pilot/sync/paging channels. A robust 32 kb/s waveform speech coder, ITU-T COM101+, has been developed to achieve toll-quality speech in the radio environment. This system provides up to 128 voice channels per cell and data transmission up to 64 kb/s by 5 MHz spreading. Unification of low-and high-mobility applications and reduced complexity of system and hardware configurations are accomplished.
