Go back and come back strong

I strongly believe in this theory. My earlier posts along similar lines has a strong correlation to this one. For the uninitiated, those in which I talk about Motivational talking and Learn, unlearn and re-learn. Rather than hovering around in a state of chaos consciously or unconsciously, its better to get off the board and re-analyze the issues at stake and come back strong. Its always a nice feeling to be a vital cog in the lineup than hanging in there and being ostracized. Lets get into a few real world situations, a packet when transmitted traverses through the channel;the noise in the channel which can be random depending on the ambience, can corrupt it at any point of time, and this is what I call the mind getting vitiated by the sorroundings in addition to the own device generated noise. The receiver based on its capability attempts to re-surrect it based on whatever redundancy it has acquired within the data - this correlates to the past sequence of states the mind has gone through and can be perceived as a finite state machine. Its also similar to a phase locked loop attempting to lock with a reference so that it comes to a conscious state of knowing itself about its lineage. There are numerous limitations to this as the magnitude of the error/noise ratio might be humongous that it requires several cycles to realize the real state of the device; based on the gain bandwidth of the loop in analog terms.So there is always a possibility of running into the so called unpredictable state and hence a palatable solution to the entire scenario might be to reset the sequence and convert the closed loop into an open one. Re-transmission is the key as the receiver, indicates aftera certain time interval of sliding through each of the time units repeatedly lookingto decipher the state of the data.

there could be a problem in the receiver as well, did you think about that. no matter how many times you reset, you are going to hit the same state.

Good point Paran but sorry about your pessimistic approach.The system has been existing for a while and has accomplished quite a few tasks with the loop back test,so consider it as a black box.Its just the channel (random) that has to be taken care of.

How about this.

Transmission has been going on in a particular manner until now. Lets redefine the fundamental mechanism.

Transmission happens with a pilot being sent(initial interest) and a small portion of the main data (initial experience). This would be different from jumping in completely and sending the entire stream without knowing the amount of noise in the device and also the channel. If the receiver cannot complete decode the message, then we know that there is some noise in the medium and the feedback about how much the receiver was able to decode indicates how much noise is in the medium. This slow yet steady mechanism is known to work all the time. It probably is the most reliable and probably the one that takes the longest, but it
works for sure :)

In hindsight, a sense of responsibility to something and somebody is all that is needed.

Aaahaaa.. Looks like I have read abt a lot of the words that u mention.. A mini recap I guess..

And reg what u posted.. Too much philosophy for me there let alone all the tech jargon
