get the picture... B-)
Synchronous Encoding is a new type of digital data
transmission that self-optimizes its own bit-rate, or speed, to the
maximum that conditions will allow...
It is a half-duplex data
transmission packet with full-duplex cross-banded, cross-linked
real-time feedback control for the fastest burst possible, which
leaves little room for interference and a lot more room for critical
Here is an how it works:
The serial bit stream from any data
source is packetized like how AX-25 protocol works, but instead of
keying the transmitter continuously, as in AFSK 1200Hz/2400Hz - 1200
b/s data stream of 1's & 0's represented in a serial data format
that is transmitted, you split the bit stream into 2 streams sending
the 1's to one radio say on 2M, and the 0's to another radio on 440,
and each bit keys on that transmitters' carrier for a prescribed time
set by the previous successful handshake signal.
Since the data stream is Manchester
Code it is self-synchronized and only transmits a bit if one changes,
ether a “1” always on 2M, or a “0” always on
440MHz, in the time-frame of a bit transmit keying-time pace set by
the flip of a bit as a marker of the window boundary to decide if
it's a “1” or a “0” that was heard from each
transmitter to complete the bit-stream on the receiving end.
Since the transmitter only needs to
transmit it's own bit state to set the virtual flip-flop on the
receiving end, it only needs to transmit long enough to set the
flip-flop, and then it is free to listen on the other radio for the
handshake reflection from the receiving ends cross-band linked transmitter on
its frequency where the bit was detected on the other band to key
the same width handshake bit on this band and frequency to be
detected by the initiator of the transmission where it immediately
sends the next bit, and the cycle repeats until all the bits for that
packet have been transmitted.
Since each radio of the 2 only send
one state of bit all the time and nothing else, it is free to listen
for the “Reflection” of the other state in real-time
cross-banded back to the initiator to send the next bit immediately
without delay of any kind, except actual conditions of the path
itself and circuit delays, so the bit stream is as fast as it possibly can go,
dynamically in real-time.
Scenario: Send a test beacon to establish a starting bit-rate, and determine the distance between transmitters... Then when sending data, the first bit depicted is a "1", so that bit keys-up the 2M rig for a very short time, as determined by a beacon test, and when the receiving party hears the carrier on its 2M rig, it breaks the squelch, which is connect directly to the keying of the 440 rig (under logic control) for the same amount of time of the receiving pulse from 2M, to be heard by the orignators 440 rig at the same time, (Almost, except for logic, propagation, and interference conditions, to slow it down, only), to trigger the immediate sending of the next bit in the data stream, until the burst is finished... So it's a half-duplex transmission with a real-time full-duplex feedback loop to reach maximum throughput, in the least amount of time...
While one radio is transmitting a
bit, the other radio listens for the reflection, and visa-versa...
Also, not only with this setup can you compute the distance between transmitters, but you can be selective on which signal to listen to based on the delay in propagation to listen to the shortest delay and lock on that signal that is closest... Or Not... You can also program the pulse-width to act as a key, like a PL tone, but in pulse-width to help ID a Station to communicate with. You can build a propagation map to ID clients in real-time, at the same time communications are happening...
Simplified Logical Function:
This concept can also be used in a different configuration such as a continuous carrier and sending AFSK instead but the power requirements for this setup is much higher because of the continuous TX power needed, where as "Reflecto-Bit" only transmits for the length of the shortest pulse possible and saving tremendous energy in the process.
To establish the shortest Pulse-Width (to be modulated) as in PWM, you send out a "Boing" which is like a "Ping" but sounds like a "Boing" because the first pulse out for a "1" bit starts the reflection timer and is sent at full carrier until the reflection is heard back which stops the reflection timer and records the longest pulse-width to complete the loop, then a "0" is sent and that PWM time is divided by 2, and another "1" is sent and that continues to send a bit stream that looks like this: "10101010101010101010..." until that pulse-width is too narrow to be detected and therefore loses a pulse, which is detected, and it reverts back to the pulse-width that did work by multiplying that time by 2 again to be back in range, but at the fastest it can go with the least amount of power required to do it, and since every machines has a personality, and signature, in the form of delay times to complete the loop, you can use the unique time frame to help ID a client system, and this is calculated and controlled for every bit sent to that station, prior to the entire short data packet burst, leaving more time for other traffic, and could run on batteries for months on end, and indefinitely with a small solar panel. Put the whole package on top of a pole, and forget it, until you need it of course...
