Abstract
Systems and methods for relaying in broadcast single-frequency networks are disclosed herein. A single-frequency network can be formed in part using transmitters that receive data via a cooperative relay channel instead of a station-to-transmitter link. In some embodiments, a second channel may use a portion of its transmission time to relay the information to the single-frequency network transmitter using time-division multiplexing. In other embodiments, a second channel may encode the relayed information on a second layer using layer-division multiplexing.
