APPARATUS AND METHOD FOR LOW COMPLEXITY COMBINATORIAL CODING OF SIGNALS

摘要

During operation of an encoder, a signal vector (x) is received. A first multi-precision operand (Psi'k) will be generated based on the signal vector to be encoded. A mantissa operand and an exponent operand are generated. Both the mantissa operand and the exponent operand are representative of a second multi-precision operand that is based on the signal vector to be encoded. A portion of Psi'k is selected to be modified based on the exponent operand. A part of Psi'k is modified based on the mantissa operand to produce a modified multi-precision operand (Psi'k+1). Finally, a multi-precision codeword is generated for use in a corresponding decoder.
