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.

A communication method for embedding a meta-carrier under an original carrier signal with reduced or minimal original carrier signal degradation, the method comprising transmitting an original carrier signal and transmitting a meta-carrier signal separate from the original carrier signal, wherein the meta-carrier signal contains information about an original carrier signal, is extractable under an interfered condition, and is transmitted such that the meta-carrier signal occupies at least a portion of a bandwidth of the original carrier signal.

A communication method for embedding a meta-carrier under an original carrier signal with reduced or minimal original carrier signal degradation, the method comprising transmitting an original carrier signal by a transmitter, forming a meta-carrier signal separate from the original carrier signal that contains meta-data about the original carrier signal including one or more characteristics of the original carrier signal configured for use by a receiving device to establish one or more parameters of a receiving device to receive the original carrier signal at the receiving device, and transmitting the meta-carrier signal by the transmitter separate from the original carrier signal such that the meta-carrier signal occupies at least a portion of a bandwidth of the original carrier signal.
摘要:
A method for remotely and dynamically controlling adjacent satellite interference comprising monitoring one or more off-axis signals emitted by one or more remote transmitters; determining whether one or more of the off-axis signals is creating adjacent satellite interference (ASI), off axis emissions and inband interference that is higher than a predetermined level of acceptable interference, and transmitting a control signal to at least one of the one or more remote transmitters in response to the determination that the one or more off-axis signals is creating interference that is higher than the predetermined level of acceptable interference, the control signal initiating an adjustment to one or more transmission parameters of the one or more remote transmitters such that interference resulting from the one or more off-axis signals emitted by the one or more remote transmitters is reduced or eliminated.
摘要:
A method of inserting meta-data into a physical layer framing structure of a Digital Video Broadcast Satellite-Generation 2 (DVB-S2) comprising encoding meta-data and an original carrier signal using an encoder, the original carrier signal having a pilot sequence, replacing, by a meta-data insertion device, at least a portion of the pilot sequence with at least a portion of the meta-data to form a meta-pilot carrier signal, modulating, using a modulator, the meta-pilot carrier signal to form a modulated meta-pilot carrier signal, and transmitting, using a transmitting device, the modulated meta-pilot carrier signal. Additionally, the meta-data may be inserted by a meta-data insertion device into at least a portion of the XFECFRAME structure when dummy-PL Frames are available when VCM and ACM operation is used.
