Abstract
A vector decoding method includes decomposing a code of an initial vector to obtain a sign code and an absolute vector code, decoding the sign code to obtain a sign vector, performing multi-level permutation-based decoding on the absolute vector code to obtain an initial absolute vector, and combining the sign vector and the initial absolute vector to obtain an initial vector, wherein each respective vector ha a plurality of elements. A vector decoding apparatus includes a decomposing unit configured to decompose a vector code to obtain a sign code and an absolute vector, a sign decoding unit configured to decode the sign code to obtain a sign vector, a multi-level permutation-based decoding unit configured to perform multi-level permutation-based decoding on the absolute vector to obtain an initial absolute vector, and a combining unit configured to combine the sign vector and the initial absolute vector to obtain an initial vector.
