摘要： A technique for providing secondary data in a single frequency network (SFN) provides a first forward error correcting (FEC) decoder for decoding a received coded orthogonal frequency division multiplex (COFDM) signal. A second FEC decoder is also provided for decoding a received COFDM signal. When the received COFDM signal includes valid primary data, the first FEC decoder is utilized to decode the received COFDM signal to provide general information, i.e., music, sports, etc. When a received COFDM signal includes valid secondary data, the second FEC decoder is utilized to decode the received COFDM signal to provide regional information, e.g., emergency broadcasting information. The received COFDM signal includes one or more defined COFDM symbols inserted by a transmitter of the COFDM signal to indicate the valid secondary data and the invalid primary data.

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.

摘要： A technique for determining a tuning frequency of an audio receiver includes interrupting a received radio frequency (RF) signal at an input of the audio receiver. Next, a modulated audio signal is injected into the input of the audio receiver. Then, it is determined whether the demodulated audio signal is present at an output of the audio receiver. If not, the frequency of the modulated audio signal is changed until the demodulated audio signal is detected at the output of the audio receiver.

摘要： High priority data and low priority digital data are transmitted as primary and secondary data in hierarchically modulated, orthogonal frequency division multiplexing (OFDM) from an earth-orbiting satellite. To enable the transmitter amplifier to be operated with less back-off from saturation without clipping, the low priority OFDM symbols have fewer samples than the high priority OFDM symbols, and the high priority samples on which the low priority samples are superimposed are selected according to a first deterministic rule using sample power comparisons of the high priority samples to concentrate the low priority samples on those high priority samples having lower (optimally, the lowest) sample power. The low priority samples are distributed on the selected high priority samples according to a second deterministic rule relating the original low priority sample order to the original high priority sample order.
