FIELD: information technology.
SUBSTANCE: input vector (x) is received during operation of the encoder. A first multi-precision operand (Ψ'k ) is generated based on the input vector to be encoded. A mantissa operand and an exponent operand are generated, both of which are representative of a second multi-precision operand which is based on the input vector to be encoded. Further, a part of Ψ'k is selected to be modified based on the exponent operand. A part of Ψ'k is modified based on the mantissa operand to produce a modified multi-precision operand (Ψ'k+1). Finally, a multi-precision codeword is generated based on the modified multi-precision operand for use in a corresponding decoder.
EFFECT: minimising computational complexity.
