The upper run is the ending "carrier" packet in the receiver, the lower pass is decoded "0".

There is a fading carrier wave - the frequency in the test track was about 75MHz.

The upper course is the modulating waveform in the transmitter ("0" and "1"), the lower waveform is the response of the superregenera-tive receiver.

Superregenerative digital channel (SDC)

 

We have developed a digital radio transmission track using a superregenerative receiver with an innovative design.

The superregenerative is a very old radio transmission system. The great advantage of The superregenerative is low cost (very simple receiver).  However, until now, the superregenerative has not been used to transmit digital data at high speed.

We managed to combine the superregenerative with digital transmission. A simple radio system has been created that ensures fairly fast data transfer.

The developed receiver has a much more complex structure than the classic one superregenerative receivers, however for modern semiconductor technology the production costs would be as for the cheapest integrated circuits. Similarly with a transmitter.  Its complexity is also not a problem.

 

The STC system has a short range, just like Bluetooth, but with mass production it would be even cheaper by the order of magnitude.

It seems that after the implementation, STC could be very useful in Internet Of Things (a simple, small and cheap receiver).

 

Below we present selected waveforms recorded while working on the system.

The coding of information in the SDC consists in changing the time between the "packages" of the transmitter. On the left a longer break between "packages", on the right shorter.

The upper pass is a modulating signal, the middle one - transmitted "carrier" packets, and the lower one - the response of the superregenerative receiver.

The gaps between the transmitted pulses can be changed smoothly to a certain extent. We translated it into multivalent modulation.

In the tested track we obtained 8-value modulation (3 bits). This gave a good binary bandwidth in terms of the carrier frequency.
