Abstract
Técnicas para procesar símbolos recibidos para un canal (de transporte) en un sistema de comunicaciones (W-CDMA). De acuerdo con el estándar W-CDMA, los bits codificados de un canal de transporte son, en primer lugar, sometidos a una concordancia de velocidad, luego a un primer de-interlazado, y luego segmentados para formar x marcos de radio, en donde x es el intervalo de tiempo de transmision (TTI) del canal de transporte. Los marcos de radio pueden ser procesados de varias maneras. En un aspecto, la concordancia de velocidad y el primer de-interlazado pueden ser aplicados a los bits codificados del canal de transporte X veces para generar un marco de radio con cada aplicacion. de acuerdo con un método, la correspondencia entre el bit codificado Xm y los bits sometidos a concordancia de velocidad Yn y entre los bits sometidos a una concordancia de velocidad yn y los bits interlazados zk puede ser computada basándose en computaciones directas o iterativas. En otros aspectos, el primer de-interlazado y la concordancia de velocidad inversa pueden ser aplicados en cada marco de radio a medida que es recibido, sin tener que esperar la recepcion de los marcos de radio remanentes en el TTI. Las correspondencias entre los símbolos recibidos zk, los símbolos de-interlazados yn, y los símbolos a una concordancia de velocidad xm pueden ser computadas. Puede lograrse una reduccion en el requerimiento de memoria intermedia, y una reduccion de las demoras del proceso, basándose en lo anterior.
