摘要： A satellite-based digital audio radio (SDAR) receiver is configured to temporarily store data that may be transmitted to the SDAR receiver at a time inconvenient to the subscriber. A memory arrangement buffers data output by a channel decoder. The SDAR receiver can use the buffered data prior to using any currently transmitted data. The buffered data is associated with buffered timing information that lags behind the current timing information associated with the currently transmitted data. The buffered data is available for use only once before a decryption subsystem receives the current timing information. If the subscriber uses the currently transmitted data, the decryption subsystem receives the current timing information. The decryption subsystem decrypts only data that is associated with timing information that is no earlier than the latest timing information received by the decryption subsystem. Accordingly, the buffered data becomes unavailable once the decryption subsystem receives the current timing information.
摘要翻译：基于卫星的数字音频无线电（SDAR）接收机被配置为临时存储可能在对用户不方便的情况下发送到SDAR接收机的数据。存储装置缓冲由信道解码器输出的数据。在使用任何当前传输的数据之前，SDAR接收器可以使用缓冲的数据。缓冲的数据与缓冲的定时信息相关联，该信息落后于与当前发送的数据相关联的当前定时信息。缓冲数据仅在解密子系统收到当前定时信息之前才可使用一次。如果订户使用当前发送的数据，则解密子系统接收当前的定时信息。解密子系统仅解密与不早于解密子系统接收到的最新定时信息的定时信息相关联的数据。因此，一旦解密子系统接收当前的定时信息，缓冲的数据就变得不可用。

摘要： A receiver system and method for switching among a plurality of antenna elements to receive a signal. At least a portion of plurality of antenna elements receive a transmitted signal, such that the transmitted signal includes a plurality of sub-channels that are transmitted in predetermined time intervals. A switching device is in communication with the plurality of antenna elements, and switches among single antenna elements to receive the transmitted signal. A controller is in communication with the switching device, and commands the switching device to select each of the antenna elements separately in predetermined periods of time based upon the predetermined time intervals of each of the sub-channels. A power level of the transmitted signal is determined during the predetermined period of time that corresponds to the predetermined time intervals, and the controller commands the switching device to switch to an antenna element based upon the determined power level.

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.
