    摘要: Fault-tolerant multicast networks via network coding comprises a digital signal operator that combines data signals multicast from multiple sources and transmits the combined data signal via a link to the next or destination node. In one aspect, the digital signal operator includes an exclusive-OR operator that performs a Boolean exclusive-OR function on the received bit streams of the multicast data from the plurality of sources.

    摘要: Systems and methods for improved photonically-assisted RF filtering. Presently, processing of wide-band RF signals involves the use of multiple specialized equipment to isolate a region of interest from the spectrum. The present invention discloses the use of a modulation system to upconvert the RF signal onto the sideband of a light source such as a laser, an optical filter sub-system comprising a plurality of filtering units that function as combinations of IIR and FIR filters, and a resonant channelizing filter for noise reduction and rejection of undesired channels, and means for control and agility of a piecewise coherent optical filter. The resulting filtered RF signal may then be downconverted to the electrical domain for further signal processing.

    摘要: A system and methods are provided for transmitting an encrypted data word of two or more bits. This involves identifying a random key word comprising two or more bits for encrypting the data word and identifying a set of unique orthogonal codes. This also involves selecting a code from the set of unique orthogonal codes that corresponds to a result of an exclusive-or (XOR) operation between the two or more bits of the data word and the random key word. This also involves encoding a signal with the code and transmitting the encoded signal as encrypted data.
