Hints

1. Minimize sum of squares of differences, not sum of absolute values of differences.

2. It is important, that constant AMP (amplitude) is the same for all bits.

3. There is no test with negative amplitude.

Hint should be:

notion of appropriate statistical processing:

extracting a and b in a+b*k from noise

Or

MNK

Or

sequental analysis

Or

maching learning

Or

optimal decision theory

What artical in Wikpedia should read?

Re: Hints

Would you be so kind to give the slightly more detailed description of your solution?

I tried to used DFT but it seems to be too sensitive to noise.

I heard of Arctan-Differentiated Demodulator, but I can't find the literature on this theme. Does anybody know, is it applicable here?

Re: Hints

Use OLS (ordinary least squares) estimator for this problem

Re: Hints

Thanks a lot. I've never used this method before. But it's worth keeping in mind :)
