  • Patent number: 8699545
    Abstract: A method of embedding and transmitting a meta-data message in an original burst carrier signal for message reassembly comprising spreading a meta-carrier signal using a Direct Sequence Spread Spectrum (DSSS) spreading code having a Pseudo-Random Noise (PRN) spreading code sequence, the meta-carrier signal comprising one or more bits of meta-data information about the original burst carrier signal, lowering a power spectral density of the meta-carrier signal using the PRN spreading code such that interference with the original signal is reduced, combining the original burst carrier and the meta-carrier signals using a modulator such that a composite burst carrier signal results wherein the meta-carrier signal occupies at least a portion of a bandwidth of the original carrier, and transmitting the composite burst carrier using a transmitter over a telecommunications channel in which only one burst carrier signal is expected to be present within a predetermined frequency bandwidth at a point in time.
