摘要

A method for codeword (220) searching (250), or for encoding speech, which method includes the steps of organizing a plurality of codewords (w) into an order which has both an Extended Grey Code Property (EGCP) and a complementary property and at an ith iteration, updating an ith version Ui of array U and an ith version Vi of array V in a recursive manner and as functions of jth versions Uj and Vj, respectively of arrays U and V, wherein j has the greatest value smaller than i for which wi and wj differ by only two bits.
