Abstract: PURPOSE: A preamble detector for CDMA receiver is provided to reduce the time necessary for detection and detect a spreading signal promptly by adapting a preamble detector for a random access channel. CONSTITUTION: A receiver inside a code division multiple access(CDMA) communication system adopts this preamble detector for a random access channel(RACH, for instance). The RACH uses an orthogonal Gold code(OGC) series for a preamble signature series and/or spreads the preamble signature series by the OGC series. The preamble detector adopts fast orthogonal Gold transformation(FOGT) in order to inversely spread the preamble signature series and also to generate a judgment statistic for detecting the signature series used inside the preamble. The spread signals of the RACH are added to a code matching filter(CMF) matching a spread OGC series and the output signals of the CMF are sampled at a symbol rate. Fast Hadamard transformation(FHT) is applied to the sampled output of the CMF.

Filed: 2000-12-22
Abstract: PURPOSE: A method for measuring a shielding capability of a magnetic anisotropic steel plate is provided, which measure the shielding capability of the steel material more accurately at a variable frequency. CONSTITUTION: After preparing a random steel material plate of a regular square having a magnetic anisotropy, a voltage(V-horizontal) over both ends of a secondary coil(103) is measured by inserting the steel plate between a pair of cores(102,104) in a yoke type faced with a constant gap each other where coils(101,103) are wound, and then a voltage(V-vertical) is measured by rotating the steel material plate by 90 deg. When there is no steel plate between the cores, a voltage(Vo) over the secondary coil is measured. Then, a shielding effectiveness of the steel plate is obtained from the above voltage ratio. The shielding effectiveness is expressed as an equation of shielding effectiveness(dB) = - 20log(V/Vo).
