With the introduction of the third generation systems
(IMT-2000), second generation capabilities (voice and
low/medium rate data) are extended adding multimedia
capabilities to second-generation platforms such as
support for high bit rates and introduction of packet
data/IP access. In this paper the technical features of the
two IMT-2000 radio interface proposals, ARIB/ETSI’s
WCDMA and TIA’s cdma2000, are discussed and a
comparison is being made regarding their performances.
After the similarities are given briefly, the study is more
focused on the differences that are affecting the
performance. Main issues of the differences are examined
in detail to find out the benefits or the drawbacks that
those issues bring to each proposal.
