Patent CA-2326934-A1 (CA)
Inventor: BUEHRER R MICHAEL
IPC: H04B1/7105
Filed: 2000-11-24
Abstract: A Code Division Multiple Access system and method of operation provides reduced interference for received signals and improved signal acquisition and processing with reduced computational complexity. The system includes a base station coupled to an antenna array of at least two or more antennas and serving a plurality of users. A receiver in the base station includes a universal inverse cross-correlation matrix coupled to the antenna array, a signal acquisition and a signal processing circuit serving each user. Each signal acquisition circuit comprises a series of delay stages in which the incoming antenna signals in each stage are correlated with a spreading code and combined in a multiplier coupled to the universal inverse cross-correlation matrix which facilitates improved time delay estimation for signal acquisition. Each multiplier combines the correlated signals of the stage with the output of the universal inverse cross-correlation matrix to provide a signal amplitude representative of the signal energy in an antenna path for a given time period, with individual delays separated by a half of chip period. The amplitudes for each of the delay stages are captured in buffers which contain threshold information for selection of the strongest received signal. The signal processing circuit combines the strongest received signal with a channel estimate and the universal inverse matrix output in a multiplier to provide an output signal for demodulation and decoding with improved signal quality due to (a) reduced interference, (b) improved synchronization for signal acquisition and processing, and (c) the universal inverse cross-correlation matrix reducing computational complexity in signal acquisition and signal processing.

Title: System and method for detecting dirty data fields
Inventor: TIU PATRICK S C
IPC: G06F17/30
Filed: 2000-11-30
Abstract: The invention relates to a system and method for indicating when changes to values of data fields in a document have occurred. In one embodiment of the invention, two objects are created upon the loading of an HTML form on an HTML page in a web browser. One object stores the initial values of the data in the HTML form, while the other object is subsequently updated so that the current values of the data in the HTML form are stored therein. When the data in the HTML form is submitted to a server, the data in the two objects are compared to determine which data fields of the HTML form are "dirty"; i.e., which data fields have current values different from their initial values. A  record identifying which data fields are "dirty" is created and is submitted to the server along with the data in the HTML page.

Abstract: A method and apparatus for achieving dynamic intensity modulation of the channels in a wavelength-division multiplexed optical communication system is presented. Wavelengths are spatially separated into a plurality of channels, the polarization states of which are individually modulated. The channels can be combined or filtered by polarization states to achieve the desired intensity in the output signal.     An exemplary embodiment includes at least a polarization modulator, a birefringent wedge, a lens, and a dispersive element (e.g., diffraction grating) arranged in various order. Each segment of the polarization modulator can be made to rotate the polarization direction of an incident channel by a specified angle. A half-wave plate may be inserted between the second dispersive element and the second birefringent wedge to eliminate polarization-dependent loss. Optionally, a parallel birefringent plate may be inserted after the second birefringent wedge to reduce polarization mode dispersion.

Title: Improved cdma soft hand-off
Inventor: CORBETT EDDIE
IPC: H04W36/30
Filed: 1999-12-14
Abstract: A system and method for improving soft hand-off in a CDMA system uses mobile station location and velocity information to maintain soft hand-off legs with those cells in which the mobile station is more likely to be located. The system and method of the present invention estimates the weighted probability of the mobile station arriving in neighboring cells and produces "bias" values for those cells that the mobile station is more likely to be entering or to be located in.  These bias values are used for modifying signal quality values for those cells, and for determinig whether the current cell or neighbor cells are to be placed in an active set so as to establish, or maintain, soft hand-off legs. The system and method of the present invention thus chooses those cells which are more likely to be retained as soft hand-off legs and therefore reduces the overall number of soft hand-offs.
