Title: Method of channel estimation based on doubly adjacent windows and apparatus thereof
Inventor: GUANGHUI LIU
IPC: H04L27/06
Filed: 2006-12-07
Abstract: A method and an apparatus for estimating a channel on the basis of doubly adjacent windows are provided to minimize noise interference by fractionizing a distribution region of a CIR(Channel Impulse Response) when estimating the CIR. An apparatus for estimating a channel on the basis of doubly adjacent windows includes a linear correlator(20) creating a correlation signal by receiving a baseband sampled complex signal and a local pseudo-noise signal and by calculating a linear correlation of the baseband sampled complex signal and the local pseudo-noise signal. A CIR estimating unit(30) removes a noise in the correlation signal by receiving the correlation signal and outputs the CIR corresponding to a result estimated through estimating the CIR. The CIR estimating unit calculates a rate of average powers of a first window and a second window achieved by scanning the correlation signal through the first window and the second window.

Title: Method for operating a gas laser system
Inventor: KILTHAU ALEXANDER
IPC: B23K26/38
Filed: 2004-04-16
Abstract: The invention relates to a method for operating a gas laser system, especially with a CO2 laser. Predetermined pulse sequences (LPF1, LPF2, LPF3) are directed in a working phase (APH1, APH2, APH3) to a determined processing point of a substrate, and then laser deflection is adjusted onto the next working point in a transfer phase (SPH1, SPH2). High frequency pump energy (RF) is applied to the laser resonator in an intermittent manner during the transfer phase (SPH1, SPH2) in order to prevent variable cooling of the laser resonator and also varying hole qualities in the holes made by the laser due to uneven distances between the processing points and corresponding uneven long transfer phases, such that the power level in the resonator is maintained at approximately the same level as during the working phases (APH1, APH2, APH3).
