Introduction
In digital communication , CellonicsTM offers a fundamental change to the way
modem solutions have traditionally been designed and built. CellonicsTM technology
introduces a simple and swift Carrier - Rate DecodingTM solution to the receiving
and decoding of a modulated signal. It encodes and decodes signals at one symbol
per cycle-a feature not found elsewhere. Its simplicity will obsolete the super
heterodyne receiver design that has been in use since its invention by Major Edward
Armstrong in 1918.In fact, according to one estimate,98 % of the worlds radio
systems are still based on this superhet design. Cellonics
Inc. has invented and patented a number of circuits that mimic the above biological
cell behavior. The CellonicsTM circuits are incredibly simple with advantages
of low-cost, low power consumption and smallness of size. When applied in communication,
the CellonicsTM technology is a fundamental modulation and demodulation technique.
The CellonicsTM receivers are used as devices that generate pulses from the received
analog signal and perform demodulation based on pulse counting Birth
Of Cellonics For the last 60 years, the
way radio receivers are designed and built has undergone amazingly little change.
Much of the current approach could be attributed to EH Armstrong, the oft -credited
Father of FM, who invented the super heterodyne method in 1918.He further developed
it into a complete FM commercial system in 1933 for use in public-radio broadcasting.
Today, more than 98% of receivers in radios, television and mobile phones use
this method. The subsystem used in the superhet
design consists of radio-frequency (RF)amplifiers mixers ,phase-lock loops ,filters,
oscillators and other components ,which are all complex ,noisy ,and power hungry.
Capturing a communications element from the air to retrieve its modulated signal
is not easy ,and a system often needs to spend thousands of carrier cycles to
recover just one bit of information .This process of demodulation is inefficient
,and newly emerging schemes result in complex chips difficult and expensive to
manufacture. So it was necessary to invent
a new demodulation circuit ,which do the job of conventional superheterodyne receiver
but at afar lesser component count, faster and lower in power consumption and
possessing greater signal robustness These requirements were met by designing
a circuit which models the biological cell behavior as explained earlier. The
technology for this, named CELLONICS ,was invented by scientists from CWC(Center
for Wireless communication) and Computational Science Department in Singapore. Principles
Of The Technology The Cellonics technology
is a revolutionary and unconventional approach based on the theory of nonlinear
dynamical systems and modeled after biological cell behavior. When used in the
field of communication, the technology has the ability to encode, transmit and
decode digital information powerfully over a variety of physical channels, be
they cables or wirelessly through air.
