Abstract: Se describe un metodo y aparato para intercalar bits en una primera secuencia. Un metodo ejemplar comprende almacenar un conjunto de valores de desplazamiento en por lo menos una tabla, aplicar en orden cada uno del conjunto de valores de desplazamiento del conjunto para identificar un par de bits adyacente en la primera secuencia de los bits para una nueva secuencia intercalada de los bits e incrementar cada uno el conjunto de valores de desplazamiento hasta que se alcance un limite superior para identificar adicionalmente pares de bits adyacentes adicionales en la primera secuencia de los bits para la nueva secuencia intercalada de los bits. La tabla es significativamente mas corta, requiriendo menos memoria que la utilizada en un intercalador convencional, particularmente un intercalador de GSM para conversacion de media proporcion.

Abstract: Techniques for efficiently performing erasure-and-single-error correction block decoding on a received block of symbols previously coded column-wise with an (N, K) linear block code and row-wise with an error detection code (e.g., a CRC code). Initially, each row of the received block is marked as either an erased row or an un-erased row. To perform erasure-and-single-error correction block decoding on the received block, a codeword corresponding to a column of the received block containing an undetected symbol error is initially identified. The location of the symbol error in the codeword is then determined based on a particular block decoding scheme and corresponding to the selected (N, K) block code. The row of the received block containing the symbol error is then marked as an erased row. Block decoding may then be performed for the received block with the newly marked erased row containing the symbol error.

Abstract: Procedimiento para realizar la decodificación de bloque en un bloque recibido de símbolos codificados previamente de columna en columna con un código de bloque lineal (N, K), y de fila en fila con un código de detección de errores, que comprende: la identificación de una palabra de código correspondiente a una columna del bloque recibido que contiene un error de símbolo no detectado mediante dicho código de detección de errores; la determinación del emplazamiento del error de símbolo no detectado en la palabra de código; el marcado de la fila del bloque recibido que contiene el error de símbolo no detectado, como fila suprimida; y la realización de la decodificación de bloque para el bloque recibido que contiene la fila marcada como suprimida.
