Abstract
A method for digital audio broadcasting comprising the steps of receiving a plurality of data bits to be transmitted, formatting the plurality of data bits into a plurality of protocol data units, inserting header bits at spaced locations within the protocol data units, and using the protocol data units to modulate a plurality of carriers to produce an output signal. The individual header bits can be positioned at evenly spaced locations in the protocol data units. A first one of the header bits can be offset from an end of the protocol data unit. A method of receiving the digital audio broadcasting signal the transmitters and receivers that operate in accordance with the methods are also provided.
