| 20130202018 | POWER LINE COMMUNCATION METHOD AND POWER LINE COMMUNICATION SYSTEM - A power line communication (PLC) method includes the steps of: programming a registration code into a micro inverter; enabling a data collector to execute a register step, which includes an operation of registering and saving the registration code to a server, through internet; enabling the data collector to send a message to the server through the internet; enabling the server to deliver an authentication code, which is relative to the registration code, to the data collector through the internet according to the message; and enabling the data collector and the micro inverter to identify each other via a power line based on the authentication code. | 2013-08-08 |
| 20130202019 | Multiple Receivers in an OFDM/OFDMA Communication System - A signal receiver is configured to receive multiple time-domain input signals. A plurality of the input signals among the multiple time-domain input signals is selected and transformed into frequency-domain signals. The frequency-domain signals is shifted in phase by a negative value of a respective reference phase, and the phase-shifted signals is combined into one signal. The combined signal is then multiplied with a stored signal to generate a signal product and transformed into a time-domain signal. | 2013-08-08 |

| 20130202021 | System and Method for Polarization De-Multiplexing in a Coherent Optical Receiver - A system and method for polarization de-multiplexing in a coherent optical receiver. De-multiplexing is achieved using a modified constant modulus algorithm (CMA) wherein filter coefficients are determined as a function of a coupling coefficient to avoid convergence of the CMA outputs. | 2013-08-08 |
| 20130202022 | METHOD AND DEVICE FOR SIGNAL PROCESSING AND APPLIED TO MICROWAVE COMMUNICATION SYSTEM - A method and a device which are for signal processing and are applied to a microwave communication system are disclosed. The method includes: performing equalization processing on each input signal by using an equalizer so as to obtain an equalized signal corresponding to the each input signal; performing phase estimation on phase noise in the equalized signal to obtain an estimated phase of the phase noise; performing phase rotation on the equalized signal to offset the estimated phase of the phase noise, so as to obtain a phase rotation signal; suppressing residual phase noise in the phase rotation signal by using a phase-locked loop so as to output an error signal and a received signal; and performing an iterative update on a filter coefficient of the equalizer by using the error signal. | 2013-08-08 |
