W-CDMA Mobile
Communications System
Supervising Editor: Keiji Tachikawa
NTT DoCoMo became the first in the world to launch a next-generation mobile phone
service that enables large-capacity communications. The W-CDMA mobile communica-
tions technology, known as one of the third-generation standard, was adopted to realize
this high-speed, high-quality service. This volume, the fruit of collective efforts made
by engineers engaged in R&D at NTT DoCoMo, is a standard technical documentation
describing the basic technologies that constitute the W-CDMA mobile communications
system in detail and individual systems that are expected to play an important role in
future implementations.
