Line 100: ==Free distance and error distribution== [[File:Recnonrecber.png\|thumb\|right\|300px\|Theoretical bit-error rate curves of encoded QPSK (recursive and non-recursive, soft decision), additive white Gaussian noise channel. Curves are small distinguished due to approximately the same free distances and weights.]] The '''free distance''' (''d'') is the minimal [[Hamming distance]] between different encoded sequences. The ''correcting capability'' (''t'') of a convolutional code is the number of errors that can be corrected by the code. It can be calculated as
