Title: Apparatus and method for extimating channel using hidden pilots in mobile communication system
Inventor: JUNG SUNG YOON
IPC: H04J13/00
Filed: 2006-09-22
Abstract: A method and an apparatus for estimating a channel using hidden pilots in a mobile communication system are provided to decrease a PAPR(Peak to Average Power Ratio) by decreasing a bandwidth loss due to a usage of a study signal. Pre-encoders(103-1 to 103-k) pre-encodes modulated user data. Hidden study signal adders(104-1 to 104-k) add hidden study signals to the pre-encoded signal. Subcarrier mappers(105-1 to 105-k) allocate the signal with the hidden study signal to a subcarrier. IFFT units(106-1 to 106-k) perform IFFT(Inverse Fast Fourier Transform) processes on the signal allocated to the subcarrier. Channel estimators(114-1 to 114-k) remove interference signals except for the hidden study signal from a received signal and estimate a channel by using the hidden study signal. An FFT unit performs an FFT(Fast Fourier Transform) process on the received signal. Receivers(115-1 to 115-k) remove the hidden study signal from the output from the FFT unit and detect an original signal by using the estimated channel.

Title: Improved screen nozzle
Inventor: DOWSETT MURRAY FRANK
IPC: B01D29/44
Filed: 2004-09-10
Abstract: A screen nozzle for a media retention screen is disclosed which includes a nipple, a bottom cover, a top cover, and a cylindrical screen element sandwiched between the top and bottom covers. The top cover is secured to the bottom cover by means of a threaded rod extending from either the bottom cover or the nipple through the interior of the screen through an aperture in the top cover with the top cover being retained in place by a nut or the like. The nipple is secured to the bottom cover by swaging and the threaded rod is welded to the bottom cover. Assembling the screen element using an internal threaded rod has two substantial advantages over existing screen nozzles. The first advantage is that there are no external welds which may damage or deform or foul the screen and which are also are potential areas of weaknesses which may be subject to corrosion. Secondly the screen element may be replaced without removing the nozzle from the screen plate. This makes repair and replacement of the screen nozzles considerably easier and also cheaper, since the nipple itself does not need to be replaced.
