1) Pre kazdu zachytenu postupnost dlzky (2^m) - 1 spravime autokorelaciu,
   pokial nenajdeme m-postupnost. Ak najdeme m-postupnost mame periodu N.

2) Zo vztahu N =  (2^m) - 1 vyratame stupen m generujuceho polynomu g(x).

3) Z 2m prvkov m-postupnosti {ci; ci+1; ... ci+2m-1} vyratame koeficienty
   generujuceho polynomu g(x) = gm*x^m + gm-1*x^m-1 + ... + g1*x + 1; gm = 1
   zo vztahu:

   | ci+m  |  |ci+m-1  ci+m   ...  ci+1   ci  | |gm-1|
   | ci+m+1|  |  ci   ci+m-1   .     .     .  | |gm-2|
   |   .   |  | ci+1     .     .     .     .  | |  . |
   |   .   |= |   .      .     .     .     .  |*|  . |
   |   .   |  |   .      .     .     .     .  | | g2 |
   |ci+2m-2|  |   .      .     .     .  ci+m-2| | g1 |
   |ci+2m-1|  |ci+m-2    .     .    ci  ci+m-1| |  1 |
