+       * Or: f = 2.0 * bit - 1.0
+       *
+       * Systematic encoding indicates that the info bit values are present in the codeword.
+       * 'info_bit_positions' may be obtained by ordering all non frozen_bit_positions in increasing order.
+       * One may extract them at their positions after a bit reversal operation.
+       * encoder -> decoder chain would need additional bit-reversal after encoding + before decoding.
+       * This is unnecessary.
