Abstract

Se proporciona un método y aparato para codificar y decodificar. Durante la codificación, los bits (202) se codifican (204) en símbolos (206) de modo que se facilite la decodificación de probabilidad máxima. Los grupos de símbolos (206) se transforman mediante ya sea intercalando por grupos cada grupo dentro de un bloque(208) y derivado en forma subsecuente un código ortogonal a partir de cada grupo (212) o derivando un código ortogonal a partir de cada grupo e intercalando en forma subsecuente por codificación cada código dentro de un bloque.A method and apparatus for encoding and decoding is provided. During encoding, bits 202 are encoded 204 into symbols 206 so that maximum probability decoding is facilitated. The groups of symbols (206) are transformed by either intercalating each group within a block (208) and subsequently deriving an orthogonal code from each group (212) or deriving an orthogonal code from each group and subsequently interleaving by encoding each code within a block.
