Abstract
Un sistema de generación de secuencia de códigos de distribución y/o descodificación compleja ("secuencia de códigos de descodificación ") usa una primera secuencia de códigos complejos que tiene al menos dos componentes y una segunda secuencia de códigos complejos que tiene al menos dos componentes. Los componentes de la primera secuencia de códigos complejos se mezclan con los correspondientes componentes de la segunda secuencia de códigos complejos para generar la secuencia de códigos de descodificación. Al hacerlo así, se obtiene una compensación entre los componentes de la secuencia de códigos de descodificación complejos para el mismo y/o diferentes usuarios. Por ejemplo, el sistema de generación de secuencia de códigos de distribución complejos puede usar un generador de códigos largos que produce una secuencia de códigos largos a partir del producto interior de un vector de código y una máscara de usuario. La secuencia de códigos largos se provee para una vía I y a una vía Q. Para producir una secuencia de códigos largos, la secuencia de códigos largos en la vía Q se retrasa para producir una segunda secuencia de códigos largos en la vía Q o un componente Q de la secuencia de códigos largos complejos. En la vía I, la secuencia de códigos largos I o el componente I de la secuencia de códigos largos complejos se multiplica con un componente I de una secuencia de códigos cortos para producir el componente I de la secuencia de códigos de descodificación complejos. En la vía Q, la secuencia de códigos largos Q se multiplica con un componente Q de la secuencia de códigos cortos para producir el componente Q de la secuencia de códigos de descodificación complejos. Como tal, la compensación entre los componentes de la secuencia de códigos de descodificación complejos entre diferentes y/o el mismo usuario es al menos el periodo del código corto. La secuencia de códigos de descodificación complejos se puede usar para distribución, descodificación, o desdistribución o descodificación de una señal de información.
