摘要： The present invention provides a method of hierarchically modulating first and second digital data streams in a broadcast system such as an SDAR system that is compatible with legacy receivers. The second digital data stream, but not the first, is provided with a non-binary pseudo-random encoding. A carrier is first modulated, e.g. QPSK, by the first digital data stream; and a second modulation is performed with the encoded second digital data stream. The encoding includes a multiplication of a matrix formed of 2, 3 or 4 consecutive bits of the secondary data stream by a matrix, e.g. a Hadamard matrix to form a product matrix having non-binary values that are used to modify consecutive symbols of the first modulation. The second modulation appears as Gaussian noise to legacy receivers over time.

摘要： A technique for demodulating secondary data from a hierarchically modulated signal includes a number of steps. A gray coded eight phase shift key (8-PSK) hierarchically modulated signal is received that includes primary data and secondary data. An imaginary portion of the signal is determined and a real portion of the signal is determined. An absolute value of the real portion of the signal may then be subtracted from an absolute value of the imaginary portion of the signal to provide the secondary data. The gray coded 8-PSK hierarchically modulated signal may be a uniform gray coded 8-PSK hierarchically modulated signal or a non-uniform gray coded 8-PSK hierarchically modulated signal.

摘要： The present invention involves a method and system for transmitting two levels of data in a hierarchical transmission schema. A first modulated signal is generated based on first input. A second modulation signal is generated based on a second input that has a data rate that is a fraction of the data rate of the first modulated signal. The second modulation signal has known instances where the second modulation signal has no energy. In a system where the first modulation is quadrature phase shift keying (QPSK), the second modulation signal can be a secondary phase offset. A receiver in the system that has a priori knowledge about the timing relationship between the first data signal and the instances when the second data signal is present will be able to detect both data signals optimally.

摘要： A method and system for communicating satellite digital radio program information for multiple satellite channels is provided. The method includes the steps of providing multiple satellite signals, and providing multiple data frames in each of the satellite signals. The method also includes the steps of providing frame synchronization symbols in each of the data frames, such that the frame synchronization symbols occurring in the satellite signals do not overlap in time with each other. The method also includes the steps of providing multiple data slots within each of the data frames, and providing satellite program information in at least one of the data slots in each data frame. The multiple data slots are positioned within each data frame relative to the frame synchronization symbol of that data frame, such that the data slots containing satellite program information in the multiple satellite signals do not overlap in time with each other.

摘要： Multiple receivers may be enabled to receive satellite-based digital audio radio (SDAR) services under a single subscription. For example, an SDAR service provider can enable multiple vehicles, a home-based digital radio, or a portable digital radio, singly or in any combination. Multiple receivers transmit information to each other. One receiver is designated as a primary receiver, and the other receivers are designated as secondary receivers. The SDAR service provider transmits a list of associated secondary receivers to the primary receiver. The primary receiver enables the associated secondary receivers to receive SDAR services by placing them in an authorized state. The secondary receivers must periodically communicate with the primary receiver to remain authorized. A secondary receiver that fails to communicate with the primary receiver within a prescribed time period is switched to an unauthorized state. In this unauthorized state, the secondary receiver no longer performs as an authorized receiver.
