Title: Apparatus for receiving of OFDM signals and Method for recovering of signals by estimating channel
Inventor: KIM DONG GYU
IPC: H04L25/03
Filed: 2000-12-06
Abstract: PURPOSE: An apparatus for receiving an OFMD signal and a method for recovering the OFMD signal by a channel estimate are provided to precisely estimate a channel feature in consideration of a sampling clock offset amount and a common phase noise from a received OFMD symbol and recover the received signal according to the estimated channel feature. CONSTITUTION: An ADC(20) converts a received signal into a digital signal. A controller(100) samples the digital signal according to a sampling clock of a determined timing and outputs it as a symbol unit. An FFT(23) transforms a symbol from the controller(100). An operational unit(200) calculates a common phase noise and sampling offset amount of the symbol from the FFT(23) and compensates for the symbol according to the calculated common phase noise and sampling offset amount. A channel estimating section(31) estimates a channel feature based on the symbol compensated by the operational unit(200). An equalizer(300) compensates for a distortion of the received signal from the FFT(23) based on a channel feature estimating value from the channel estimating section(31).

Title: Liquid crystal display device
Inventor: TAKAFUJI YUTAKA
IPC: G09G3/36
Filed: 2000-12-07
Abstract: PURPOSE: A liquid crystal display device is provided to be capable of performing a high-quality display. CONSTITUTION: An a-Si film(12) becoming the active layer of a TFT is crystallized into polycrystal Si by enhancing a crystal growth length while adding Ni into the film(12). As a result, a TFT having mobility being roughly times to 2.5 times of the conventional high-temperature polysilicon TFT is obtained. Thus, an operating speed equal to or faster than the double of the speed of a driving circuit incorporated type panel in which conventional TFTs are used is realized by constituting a driving circuit incorporated type panel while using these TFTs. That is, when this driving circuit incorporated type panel is used, the high-quality display is obtained without increasing the scale of external circuits and without complexing a horizontal driving circuit by preventing flicker while raising a frame frequency to roughly the two times at the time of performing a frame inversion driving.
