Patent number: 8929365Abstract: 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.Type: GrantFiled: February 23, 2009Date of Patent: January 6, 2015Assignee: Telcordia Technologies, Inc.Inventors: Ronald Charles Menendez, Joel Wright Gannett

Patent number: 8521036Abstract: The invention is directed to code labeling in an optical network. The network includes a transmitting station operable to transmit an optical signal. The network also includes an encoder coupled to the transmitting station operable to label the optical signal composed of a group of codes. A receiving station operable to receive the labeled group of optical codes is also provided. The receiving station is operable to read the optical signal if the label of the received group of codes corresponds to the group of codes assigned to the receiving station.Type: GrantFiled: July 1, 2010Date of Patent: August 27, 2013Assignee: TTI Inventions E LLCInventor: Ronald Charles Menendez

Patent number: 8472806Abstract: 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.Type: GrantFiled: April 24, 2008Date of Patent: June 25, 2013Assignee: Telcordia Technologies, Inc.Inventors: Ted Woodward, Thomas Banwell, Ronald Charles Menendez

Patent number: 8406423Abstract: 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.Type: GrantFiled: March 16, 2010Date of Patent: March 26, 2013Assignee: Telcordia Technologies, Inc.Inventor: Ronald Charles Menendez

Patent number: 7809267Abstract: The present invention is directed to a coherent gated receiver. The receiver includes a decoder operable to receive an optical signal and generate a decoded optical signal, the decoder comprises a demultiplexer operable to spatially distribute the optical signal, a phase mask operable to decode the spatially distributed optical signal, and a multiplexer operable to combine the decoded spatially distributed optical signal. The receiver also includes a laser source operable to provide a pulse signal, a combiner coupled to the laser source and the decoder operable to combine the decoded optical signal and the pulse signal, and a detector operable to detect an output from the combiner.Type: GrantFiled: June 1, 2006Date of Patent: October 5, 2010Assignee: Telcordia Technologies, Inc.Inventor: Ronald Charles Menendez

Publication number: 20100221009Abstract: Apparatus and system for transmitting and receiving optical code division multiple access data over an optical network. The apparatus comprises a spectral phase decoder for decoding the encoded optical signal to produce a decoded signal, a time gate for temporally extracting a user signal from the decoded signal, and a demodulator that is operable to extract user data from the user signal. The system preferably comprises a source for generating a sequence of optical pulses, each optical pulse comprising a plurality of spectral lines uniformly spaced in frequency so as to define a frequency bin, a data modulator associated with a subscriber and operable to modulate the sequence of pulses using subscriber data to produce a modulated data signals and a Hadamard encoder associated with the data modulator and operable to spectrally encode the modulated data signal to produce an encoded data signal.Type: ApplicationFiled: February 22, 2010Publication date: September 2, 2010Applicants: TELCORDIA TECHNOLOGIES, INC., University of Central Florida Research Foundation, Inc.

Patent number: 7773882Abstract: Communication is provided between at least two of a plurality of stations. A signal is received from a first one of the plurality of stations, and the signal is coded using a first code that is assigned to that station. The coded signal is converted to obtain a further coded signal that is decodable using a further code that is assigned to at least a second one of the plurality of stations. The further coded signal is transmitted for delivery to at least the second one of the plurality of stations.Type: GrantFiled: May 26, 2005Date of Patent: August 10, 2010Assignee: Telcordia Technologies, Inc.Inventor: Ronald Charles Menendez
