Communication Equipment-Spread Spectrum Communication Set

Spread spectrum is one of information transmission means. The
spread spectrum communication set modulates useful information
by use of a group of spectrum spreading codes. After spectrum is
spread, the signal is turned into wide band signal with low power
spectral density which is sent for transmission. The spreading of the
frequency band is realized by coded modulation and is independent
of information to be transmitted. In the receiving terminal, the signal
is de-spread through correlative demodulation by use of the same
spreading codes, thereby recovering the transmitted information.
The Spread Spectrum Communication Set Model CEC-2400 has the
following advantages:

��" Excellent anti-interference/jamming performance,
��" Desired noise suppression performance,
��" Good concealment, not to interfere with surrounding electronics,
��" High frequency band utilization factor,
��" Able to realize CDMA.
