Abstract

En un sistema OFDM, los entrelaces multiples (M) se definen para conjuntos de sub-bandas de frecuencia que no se superponen M, y también se definen las ranuras M con índices fijos. Los flujos de datos y las ondas piloto se distribuyen en ranuras que, a su vez, son distribuidas en entrelaces en base a un esquema de distribucion ranura-a-entrelace que puede lograr diversidad de frecuencia y un buen rendimiento para todas las ranuras. En un transmisor, un conversor ranura-a-entrelace distribuye las ranuras en los entrelaces. El conversor ranura-a-entrelace incluye varios multiplexores y una unidad de control. Los multiplexores distribuyen las ranuras M en los entrelaces M en base a un esquema de distribucion ranura-a-entrelace. La unidad de control genera, por lo menos una senal de control para los multiplexores. Los multiplexores pueden ordenarse y controlarse de distintas maneras segun el esquema de distribucion ranura-a-entrelace. En un receptor, un conversor entrelace- a-ranura complementario distribuye los entrelaces en las ranuras.
