Patent TW-200514974-A (TW)
Title: A method for continuously measuring the damping ratio of structural systems
Inventor: LI WEN-LUNG
IPC: G01M7/02
Filed: 2003-10-17
Abstract: The present patent is a method for measuring the damping ratio of a structural system that is under base excitations. The method is accomplished by processing the response signal with respect to that of the input. In other words, one is to measure the responses of the system, which is excited by an input sinusoidal signal. Once the response signal is obtained, it is modulated by two different reference signals. The first one is the row input signal, while the second one is the phase-shifted input signal. The proposed phase given here is 90 degrees. The two modulated output signals are then put into the low-pass filter separately and their dc values are the ones the present method required. Dividing the dc values each other to get the tangent value of the phase lag, which is due the system damping ratio, one is able to use the equation provided to calculate the required damping ratio. Because the present method is based on the phase angle of the steady-state responses, it can be adopted and displayed in real time. In addition, the current method does not require the system damping to be small and valid for a wide range of damping ratios.

Title: Channel estimation for OFDM communication systems
Inventor: KRISHNAN RANGANATHAN
IPC: H04W52/32
Filed: 2003-10-29
Abstract: Techniques to estimate the frequency response of a wireless channel in an OFDM system. In one method, an initial estimate of the frequency response of the wireless channel is obtained for a first group of subbands based on a pilot transmission received via the subbands in the first group. An estimate of the impulse response of the wireless channel is then derived based on the initial frequency response estimate. An enhanced estimate of the frequency response of the wireless channel is then derived for a second group of subbands based on the impulse response estimate. The first and second groups may each include all or only a subset of the usable subbands. Subband multiplexing may be used to allow simultaneous pilot transmissions by multiple terminals on their associated groups of subbands.
