Title: System, method and apparatus for wireless channel parameter estimation in spread spectrum communication systems
Inventor: MADKOUR MOHAMED F
IPC: H04W24/02
Filed: 2001-12-14
Granted: 2004-06-01
Abstract: The present invention provides a system, method and apparatus for estimating channel parameters in spread spectrum communication systems. A first method is accomplished by receiving a base station signal and then demodulating the base station signal. After demodulating the base station signal, a maximum signal is selected from the base station signal. If the maximum signal is the common pilot channel, then the channel parameters are estimated directly from the common pilot channel. If the maximum signal is not the common pilot channel, then the demodulated base station signal is iteratively fed back for further demodulation and re-selection of the maximum signal until the maximum signal is the common pilot channel. A second method is accomplished by incorporating channel estimates made from the interfering signals in a constructive manner to the first method.

Title: Transistor device testing employing virtual device fixturing
Inventor: LAUREANTI STEVEN J
IPC: G01R31/28
Filed: 2001-12-20
Granted: 2003-11-21
Abstract: Virtual device fixturing is used to test transistor products, such as LDMOS power amplifier products, in the final packaging and testing stage of device fabrication.

The impedance matching function, normally performed by the physical input and output impedance transformation networks of the fixture, is supplanted by de-embedded scatter parameter calibration files. Test equipment, such as a vector network analyzer, attaches to a universal test fixture, while the software scatter parameter components are responsible for making the calibrations necessary to present the device under test with a matching low impedance.

Title: Improved block transform and quantization for image and video coding
Inventor: MALVAR HENRIQUE S
IPC: H04N1/41
Filed: 2002-09-18
Granted: 2004-09-21
Abstract: An improved method and block transform for image or video encoding and decoding, wherein transformation and inverse transformation matrixes are defined such that computational complexity is significantly reduced when encoding and decoding. For example, in the two-dimensional inverse transformation of de-quantized transform coefficients into output pixel information during decoding, only four additions plus one shift operation are needed, per co-efficient transformation, all in sixteen-bit arithmetic. Transformations provide correct results because quantization during encoding and de-quantization (sixteen bits) during decoding, via the use of one of three tables selected based on each coefficient's position, have parameter values that already compensate for factors of other transformation multiplications, except for those of a power of two, (e.g., two or one-half), which are performed by a shift operation during the transformation and inverse transformation processes. Computational complexity is significantly reduced with respect to other known transforms without adversely impacting compression or quality.

Abstract: There is provided a semiconductor device which is formed on a semiconductor substrate and allows effective use of the feature of the semiconductor substrate, and there is also provided a method of manufacturing the same. An N-channel MOS transistor including a P-type body layer (3a), and a P-type active layer (6) for body voltage application which is in contact with the P-type body layer (3a) are formed on an SOI substrate which is formed to align a <110> crystal direction of a support substrate (1) with a <100> crystal direction of an SOI layer (3). A path connecting the P-type body layer (3a) and the P-type active layer (6) for body voltage application is aligned parallel to the <100> crystal direction of the SOI layer (3).
