1. coding method, at a distance of the position of x bit the Bit String of input signal is being divided into high order bit string and low-order bit string with minimum effective bit, carry out the variable length code of described high order bit string, and carry out the fixed-length code (FLC) of described low-order bit string, described coding method may further comprise the steps:

  • Derivation is near 2 xThe reference integer I of (x=m/2, m are the integers more than or equal to

         0);

    Acquisition is describedly carried out division arithmetic and definite quotient and the remainder with reference to integer I to the numerical value of being represented by Bit String respectively by using;

    AndThe variable length code of each merchant among the merchant of two successive bits strings of execution, combination are corresponding to the fixed-length code (FLC) of described merchant'"'"'s remainder and execution result, and the generation code word.
