    Abstract: Systems and methods for communication using hybrid signals are disclosed. In one aspect an apparatus for communication includes a processing system configured to encode a first set of information in a plurality of symbols and to encode a second set of information according to a spacing among the symbols. The apparatus may further comprise a transmitter configured to transmit to a device the symbols with the spacing among the symbols. In another aspect, an apparatus for communication includes a processing system configured to decode a first set of information from a plurality of symbols encoded with the first set of information or a second set of information from a spacing among the symbols by determining the spacing among the symbols. The apparatus may further comprise a receiver configured to receive the symbols via a wireless communication.

    Abstract: A signal acquisition system efficiently acquires a transmitted signal even at very low power. The system may synchronize to a preamble structure in the transmitted signal and, for example, determine timing parameters that locate the preamble with respect to system timing or other clock references. The system is particularly effective at acquiring weak power signals and is also robust against significant noise and other impairments, and therefore improves the ability of a receiving device that incorporates the signal acquisition system to acquire the signal and establish communication with other devices.

    Abstract: Time synchronization between a control center and transmitters in a single frequency network is provided by generating and receiving a first reference time signal with a high time and frequency accuracy in a short and long time horizon and a second reference time signal supplied to the control center with a low time and frequency accuracy in the short time horizon and a high time and frequency accuracy in the long time horizon. A transport data stream is generated and supplied to the transmitters with a time-variable data rate through the control center corresponding to a frequency of the second reference time signal. Time displacement of the transport data stream received from the control center is performed by a respective transmitter until the data packets of the transport data stream each containing a transmission time are transmitted at a correct transmission time.
