Title: Polarization mode dispersion compensation method and polarization mode dispersion compensation apparatus
Inventor: KISAKA YOSHIAKI
IPC: H04B10/2569
Filed: 2003-07-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a polarization mode dispersion compensation method and a polarization mode dispersion compensation apparatus in which deterioration of a transmission quality caused by primary PMD (polarization mode dispersion) is stably compensated without limiting a compensation DGD (differential group delay) value even in a system where a main polarization axis of an optical transmission line changes with the lapse of time.  <P>SOLUTION: Signal light transmitted by an optical transmitter 5 is propagated along an optical transmission path 6, passed through a polarization converting means 1 and then inputted to a specific polarization selecting means 2. In the inputted signal light, a specific polarization component is separated by the specific polarization selecting means 2. When the separated signal light is inputted, a waveform deterioration detecting means 3 detects waveform deterioration. Based upon information on the detected waveform deterioration, a control means 7 controls the polarization converting means 1 so as to minimize the waveform deterioration.  <P>COPYRIGHT: (C)2004,JPO

Title: Spectrum shaping and waveform equalization method for ofdm
Inventor: HATTORI TAKESHI
IPC: H04B7/005
Filed: 2003-07-09
Abstract: <P>PROBLEM TO BE SOLVED: To solve problems such that transmission efficiency is lowered by requiring increase of a guard time when trying to reduce an out-of-band spectrum in a conventional windowing configuration, and that a frequency utilization rate is lowered by requiring increase of channel intervals between adjacent channels when not increasing the guard time.  <P>SOLUTION: This method is an over-windowing method for windowing over symbols to suppress the out-of-band spectrum in an OFDM system and an equalization method for equalizing the waveform distortion caused by over-windowing on a receiving side. The windowing is performed over the section not only the guard time but also over the symbols thereby enhancing a spectrum shaping effect, and inverse windowing properties and a received signal are multiplied on the receiving side thereby equalizing the waveform distortion.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
