In digital communication, CellonicsTM offers a fundamental change in the way modem solutions have been traditionally designed and built. CellonicsTM technology introduces a simple and fast Carrier-Rate DecodingTM solution for the reception and decoding of a modulated signal. It encodes and decodes the signals with one symbol per cycle, a characteristic that is not found anywhere else. Its obsolete simplicity is the design of the super heterodyne receiver 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 series of circuits that mimic previous biological cell behavior. CellonicsTM circuits are incredibly simple with advantages of low cost, low energy consumption and small size. When applied in communication, 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 the pulse count.
Over the past 60 years, the way radio receivers have been designed and built has undergone amazingly few changes. Much of the current focus could be attributed to EH Armstrong, the father of FM, who was the father of FM, who invented the super heterodyne method in 1918. He developed it in 1933 to be used in public broadcasting. Today, more than 98% of the receivers on radios, television and mobile phones use this method. The subsystem used in the Superhet design consists of radio frequency amplifier (RF) mixers, phase-locked loops, filters, oscillators and other components, all complex, noisy and very energetic. 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 retrieve only one bit of information. This demodulation process is inefficient and newly emerging schemes result in complex chips. Difficult and expensive to manufacture.
Therefore, it was necessary to invent a new demodulation circuit, which does the work of a conventional superheterodyne receiver, but at a lower component count, faster and lower in power consumption and possess greater signal strength. These requirements were fulfilled Designing a circuit that models the biological cell As explained above. The technology for this, called CELLONICS, was invented by scientists from the CWC (Wireless Communication Center) and the Department of Computer Science in Singapore.
Principles of technology
Cellonics technology is a revolutionary and unconventional approach based on the theory of nonlinear dynamical systems and modelled after biological cellular behavior. When used in the field of communication, technology has the ability to encode, transmit and decode digital information powerfully over a variety of physical channels, either wires or wirelessly through the air.
