    Abstract: A method comprises partitioning a data object into a sequence of nested data objects each including fragments having K symbols per fragment. The method further comprises processing the nested data objects to produce sequences of coded payloads corresponding to the nested data objects. The processing includes, for each nested data object: using (n, K) coding for which n>K, individually coding the fragments of the nested data object into codewords with n codeword symbols per codeword; and generating, from the codewords, a sequence of coded payloads that are unique for the nested data object. The method further comprises transmitting coded payloads of the sequences of coded payloads.

    IPC: H04H20/30

    Abstract: A radio transmitter comprises transmitting circuitry and processing circuitry. The transmitting circuitry broadcasts a frequency modulation (FM) in-band on-channel (IBOC) radio signal, wherein the FM IBOC radio signal includes multiple subcarriers grouped into multiple frequency partitions. The processing circuitry is configured to receive input bits for transmitting; encode and puncture the input bits using forward error correction (FEC) encoding; distribute encoded input bits between a main encoded component and a backup encoded component, wherein encoded bits of the backup encoded component are delayed for a specified duration relative to encoded bits of the main encoded component; allocate the encoded input bits of the main and backup encoded components into frequency diverse sidebands of the FM IBOC radio signal; and modulate the encoded input bits for transmitting using the frequency diverse sidebands of the FM IBOC radio signal, wherein the modulation is a type of quadrature amplitude modulation (QAM).

    Abstract: Systems and methods are disclosed for communicating an emergency alert message from a digital radio broadcast transmission system of a mobile vehicle to a digital radio broadcast receiver system. A digital radio broadcast signal including first and second data is broadcasted using the digital radio broadcast transmission system to end-user digital radio broadcast receivers. The first data includes an emergency code, and the second data includes an emergency alert message. The digital radio broadcast signal is transmitted at a predetermined frequency that is recognized by the receivers as an emergency notification frequency. The digital radio broadcast signal can be decoded only by receivers located within a localized area in a proximity of the transmission system. The receivers are configured to automatically tune to the emergency notification frequency to receive the digital radio broadcast signal and render the second data based on a detection of the emergency code within the signal.

    Abstract: A method of block deinterleaving data received at a digital radio broadcast receiver is described. The method includes providing a block of memory having n x k addresses, wherein the block comprises a single table, receiving a digital radio broadcast signal at the receiver, and demodulating the digital radio broadcast signal into a plurality of interleaved data units. For at least one series of n x k data units a pointer step size is determined, and for each data unit in the series, an address in the block is calculated based on the pointer step size, and an output data unit is read from the block at the address, such that said output data units represent block deinterieaved data units. An input data unit from the plurality of interleaved data units is then written to the block at the address. Associated systems and computer readable storage media are presented.
