Latest Patents

Feldman's latest patents include a "System and method for code division multiplexed optical communication." This invention involves a system for optical communication that forms a family of orthogonal optical codes modulated by a data stream. The orthogonal codes are created by generating a stream of evenly spaced pulses using a pulse spreader circuit. These pulses are then modulated in amplitude and/or phase to create a family of orthogonal optical code words, each representing a symbol. A spreader calibration circuit ensures accurate timing and modulation. Each code word is further modulated by a predetermined number of data bits, with the data modulation scheme splitting a code word into horizontal and vertical components. These components are processed prior to modulation with data and recombined with a polarization beam combiner. The data-modulated code word is transmitted to the receiver, where it is detected and demodulated with the help of a symbol synchronization unit. A polarization mode distortion compensator at the receiver works in conjunction with a state of polarization compensator at the transmitter to mitigate polarization distortion in the fiber.

Another significant patent is the "System and method for orthogonal frequency division multiplexed optical communication." This system sends optical signals over multiple wavelength channels, with each channel comprising several orthogonal subchannel frequencies spaced apart by a predetermined amount. Each subchannel frequency is modulated with data from a data stream. The data modulation scheme splits a subchannel frequency code into horizontal and vertical components, which are processed before modulation with data. The various data-modulated subchannels are combined into a single channel for transmission. The received signals are detected and demodulated using a symbol timing recovery module, which establishes the beginning and end of each symbol. A polarization mode distortion compensation module at the receiver mitigates the effects of polarization mode distortion in the fiber.
