Abstract: A technique for providing secondary data in a single frequency network (SFN) provides a first forward error correcting (FEC) decoder (208) for decoding a received coded orthogonal frequency division multiplex (COFDM) signal. A second FEC decoder (208A) is also provided for decoding a received COFDM signal. When the received COFDM signal includes valid primary data, the first FEC decoder (208) 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 (208A) 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.

Abstract: An antenna assembly (12), a receiver (14), and a system (10) configured to superimpose a first received signal (32) from a first antenna (26) and an intermediate signal (52) based on a second received signal (34) from a second antenna (28) onto a single cable (40). The antenna assembly (12) includes a mixer (48) and an adjustable local oscillator (54) (ALO (54)) that frequency shift the second received signal (34) to generate the intermediate signal (52). The output frequency of the ALO (54) is controlled by a control signal (56) superimposed on the single cable (40) that is output by the receiver (14). With this arrangement, a plurality of antennas or antenna elements (26. 28. 30) can be connected to a receiver (14) using a single coaxial cable. Such an arrangement is particularly desirable to manufacturers of automobiles and other vehicles. Also, the receiver (14) can detect if the output frequency of the ALO (54) needs to be adjusted, and so close-loop control of the output frequency is possible.

Abstract: A communication system (10) configured to communicate receiver-specific information (26) from a transmitter (18) to a plurality of receivers (12). Each of the receivers (12) is assigned to one of a plurality of groups based on a group identification value stored in each receiver (12). A first receiver group (12A) is configured to operate during a first information-expected time interval (34A). The first information-expected time interval (34A) is determined based on a reception time (36) of a time-reference signal (24) and a first group identification value (42A). A second receiver group (12B) is configured to operate during a second information-expected time interval (34B) distinct from the first information-expected time interval (34A). The second information-expected time interval (34B) is determined based on the reception time (36) of the time-reference signal (24) and a second group identification value (42B).

Abstract: A satellite communication system (10) using hierarchical modulation to transmit a plurality of modulated signals (12) to sub-regions (16) within a region (14). Each modulated signal includes high priority content and low priority content. The system (10) includes a satellite (20) equipped with a plurality of satellite transmitters (22) coupled to a plurality of antenna elements (24), e.g. a phased array of antenna elements (24). The antenna elements (24) are utilized selectively to direct a modulated signal from a satellite (20) transmitter to a distinct sub-region (16a). The satellite transmitters (22) and antenna also cooperate to broadcast the high-priority content to the region (14) such that a ground receiver (30) traveling from a first sub-region (16a) to an adjacent second sub-region (16b) adjacent will not experience a loss of high-priority content. First low-priority content of a first modulated signal (12a) directed to the first sub-region (16a) is independent of second low-priority content of a second modulated signal (12b) directed to the second sub-region (16b).
