Latest Patents

Li Guoliang holds a patent titled "System and method for code division multiplexed optical communication." This invention describes a system for optical communication that utilizes 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 form 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 using a polarization beam combiner. The data-modulated code word is transmitted to the receiver, where it is detected and demodulated with the assistance of a symbol synchronization unit. This unit establishes the beginning and end of the code words. Additionally, 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.
