I. Product Features
CDMA mobile communication principle experiment apparatus is tightly
close to such teaching syllabus as Spread
Spectrum Communication. The experiment contents are comprehensive, which
could fully meet Experiment teaching requirements of such course as spread
spectrum mobile communication on communication’ major among colleges and
universities.
(1)
The experiment apparatus has designed a complete direct-spread code-division multiple
access (DS-CDMA) mobile communication system, which realizes wireless
transceiver by carrier and tightly combines textbook of Spread Spectrum Communication, and outlines the key points of
textbook, such as GOLD sequence, spread spectrum and despread spectrum, acquisition
and tracking, synchronization extraction, error correction encoding and so on,
enabling users to further understand the essence of CDMA by experiments.
(2)
CDMA system includes many functions, such as direct spread spectrum and
despread spectrum, code division multiple access, acquisition and tracking of pseudo-random
sequence, bit synchronization, frame synchronization extraction, carrier
recovery, error correction coding and encoding, which could compose a complete
CDMA mobile communication system. Simultaneously, it could establish big CDMA
system between two or multiple experiment apparatuss through wireless
transmission.
(3) Adopt plexiglass baffle for protection
