INTRODUCTION
The new modulation and demodulation technology is called Cellonics.
It is based on the way biological cells communicate with each other and nonlinear dynamical systems (NDS).
The ASCII uses a combination of ones and zeros to display a single letter of the alphabet The data is sent over radio frequency cycle to its destination where it is then decoded.



INTRODUCTION
Human cells respond to stimuli and generate waveforms that consist of a continuous line of pulses separated by periods of silence. The Cellonics technology uses these pulse signals and apply them to the communications industry.
Cellonics allow the modem speeds of 1,000 times faster than our present modems.
Benefits are incredible speed, simplicity, and robustness.




PRINCIPLE OF CELLONICS TECHNOLOGY
Cellonics technology came about after studying biological cell behavior.
It has the ability to encode, transmit and decode digital information over a variety of physical channels, be cables or wirelessly through the air.
A Circuit can accept an analog input waveform and output a set of pulse trains with predictable number of pulses in each burst.

The slow waveforms trigger the fast pulse trains allowing the cells to convey information.
Slow waveforms: Analogue waveforms that vary slowly with time. These waveforms can be in any arbitrary shape
Fast waveforms/fast pulse trains: Waveform in the shape of pulses that varies rapidly with time.




CELLONICS CIRCUIT
S curve transfer characteristic.
Transfer characteristic consists of three different regions.
The two lines at the top and bottom have positive slope.
1/RF and they represent the regions in which the Op-Amp is operating in the saturated (nonlinear) mode.
The middle segment has a negative slope(Op-Amp operate linearly).
dVs/dt = (V0 depending on the slope of the triangular input waveform).
slope is positive, the Op-Amp is stable- outputs a constant saturation voltage.
When slope is negative- the Op-Amp is unstable- the output is oscillating.
By controlling the duration of the negative slope, he number of pulses to be produced at the output of the Op-Amp can be controlled.
The transfer function of a tunnel diode exhibits the N- curve. By connecting an inductor and a tunnel diode in series, we can produce pulses that are separated by periods of silence.





APPLICATIONS TO TELECOMMUNICATION
Cellonics is a most powerful demodulation technique and it inherent Carrier-rate Decoding.
In Cellonics technology, information can be decoded in every transmitted cycle. Thus, this breakthrough promises very high-speed data transmission





PERFORMANCE OF CELLONICS RECEIVER
An important performance measure of any modulation scheme is its bit-error rate (BER) performance in a noisy channel.



Ultra Wideband Video System
Transmits real-time video images at a data rate of 12Mbps wirelessly to a video monitor.
A simple web camera is used as the video capture source. The digital video information is fed into a pulse position modulation processing board (a Field Programmable Gate Array or FPGA board) via a USB connection before being frequency translated to a higher frequency band at a transmitter for sending over the air. The airborne signals are then detected by a UWB receiver and pulse position demodulated back into digital video information for display at a video monitor. In both instances, an ultra simple Cellonics Transmitter and a simple Celloncis receiver are used. The speed of the system is only limited by the Video cameraâ„¢s USB interface data rate.
