Abstract
Se proporcionan componentes y metodo para procesar eficientemente datos de comunicaciones inalambricas donde el conocimiento previo del formato especifico de los datos de comunicacion no esta disponible. Una unidad de transmision y recepcion inalambrica (WTRU) es configurada para usarse en un sistema de comunicacion inalambrica donde los datos de comunicacion para canales seleccionados son transmitidos en cuadros de tiempo del sistema en formatos seleccionados de un conjunto de formatos predefinidos. La WTRU tiene un receptor, una memoria, un procesador de la velocidad de microcircuito integrado recibida (RCRP), un detector de formato y un desintercalador. El RCRP esta configurado preferiblemente para compensar por propagacion cada senal inalambrica de los datos propagados recibidos en cada cuadro de tiempo usando un codigo de propagacion minimo u otra secuencia de claves apropiada y para almacenar los datos compensados por propagacion resultantes por cada cuadro de tiempo respectivo en la memoria. El detector de formato esta configurado preferiblemente para determinar el numero de canales fisicos y el factor de propagacion respectivo por cada canal fisico para la senal inalambrica de los datos propagados recibidos en cada cuadro de tiempo. El desintercalador esta configurado preferiblemente para desintercalar almacenados compensados por propagacion por el RCRP por cada cuadro de tiempo respectivo en el numero de canales fisicos determinados por el detector de formato por el cuadro de tiempo respectivo.
