Re: [digitalradio] CW decoding comparison (MPSK, Mixw, Hamscope)
Hello to all, Here is an extract of one of my paper (aboutCCW). 73 Patrick Problems with the automatic decoding of the traditional Morse For a computer, Morse is seen as a sequence of bits having either "0" or "1" for value, a bit being as long as a dot. For example, the letter "A" (di dah followed by a 3 dots duration blank or '- --- ') will be recognized as being the sequence '10111000', if, conventionally, the value "0" is associated to the absence of carrier and the value "1" to the presence of carrier. If all CW transmissions would be standardized on the characteristics of character keying and speed (say 20 wpm), the decoding would not be complicated. However, in the reality, characters are keyed in a more or less regular way and the speed can be situated between 10 and 50 wpm and may vary during the QSO. So, the decoder cannot rely on a definite bit duration and must then, permanently, determines the more probable bit duration, which makes the decoding difficult. This is why, at the present time, the CW decoding by Morse specialist is better than software decoding . Note: to equal the human decoding, it would be necessary, no doubt, to abandon the bit notion and to recognize CCW characters in the same way as characters written by hand are, I mean with neural networks leaning on a learning realized upon a set of different types of keying, speeds and signal-to-noise ratios...a big program! - Original Message - From: F.R.

None of the above!
