摘要： A method of reducing signal correlation in a symmetrical adaptive canceller link comprising spectrally inverting one of a first carrier signal and a second carrier signal by causing a spectral inversion of one of the first and second carrier signals using a modulator, transmitting the first and second carrier signals within a bandwidth to a remote receiver using a transmitting device such that a composite carrier signal results, and cancelling at least one of the first carrier signal from the composite carrier signal using a cancellation technique such that the second carrier signal results on one end of the link and the second carrier signal from the composite carrier signal using a cancellation technique such that the first carrier signal results on the opposite end of the link.

摘要： A method of receiving and reassembling non-sequential meta-data information embedded within an original burst carrier signal that receives multiple composite burst carrier signals each with an original burst carrier signal and a meta-carrier signal, wherein the meta-carrier signal occupies at least a portion of a bandwidth of the original burst carrier signal and includes one or more bits of meta-data information of a meta-data message about the original burst carrier signal that is non-contiguous in reference to a temporal order in which the meta-data information is received, detecting a DSSS spreading sequence and extracting the meta-carrier signals from the composite burst carrier signals, determining a phase progression of the meta-carrier signals based on a PRN spreading code, and reassembling the one or more bits of meta-data information from each meta-carrier signal into a sequential order after an entire meta-data message is received and extracted.

摘要： 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.
