Abstract: In the reception of a CDMA signal, the receiving unit performs a simplified process of linear equalization that eliminates the need for inverting the correlation matrix. For the single antenna reception case, the correlation matrix is approximated to a good degree by a circulation matrix that is diagonalized by FFT operations, thus substituting two FFTs and one IFFT having a complexity of O(3/2 LF log LF) for the direct matrix inversion having a complexity of O(LF3). The extension of this method uses a multiple antenna reception system with oversampling.

Abstract: The present invention provides systems and methods that facilitate transmission and/or reception of radio frequency (RF) signals within a mobile communications device. The systems and methods include a first antenna component such as an active stub that comprises one or more active elements and a second antenna component such as a parasitic whip that is electromagnetically coupled to the first antenna component. The systems and methods provide a relatively compact antenna structure for mobile devices with limited physical volume, or footprint. The antenna structure does not require a mechanical interface (e.g., a galvanic connection) between the active stub and parasitic whip to provide a conductive connection to the whip when it is in an extended position. The novel systems and methods yield reduced antenna wear, higher antenna gain and better radiation efficiency than conventional systems and do not require a matching circuit to achieve multi-band resonances.

Abstract: A software security system is arranged to verify the authenticity of each element of a Java Virtual Machine installation. A digital signature is attached to each file of the JVM installation. A loader (20) verifies the digital signature of the JVM DLL (30). The JVM DLL 30 then verifies the digital signature of each other DLL and configuration file to be loaded (40, 50, 60, 70), and only loads those files which have successfully verified digital signatures. In this way the security of the JVM is enhanced, a user has greater confidence that the Java applications will function correctly, and the detection of incorrect or damaged JVM installations is improved.

Abstract: A scene is imaged by moving an optical lens relative to an image sensing surface (such as film or a pixel array) synchronously with exposing different portions of the image sensing surface. The synchronous actions are preferably adaptable to the scene being imaged, so objects at different object distances are focused at different times and exposed to different portions of the sensing surface at different times within an exposure frame period. Exposure time for the different portions of the sensor may be varied according to speed or brightness of the different objects in the scene to be imaged, as detected at the camera by measuring apparatus similar to auto focus distance measuring apparatus. A camera and a program of computer readable instructions are also detailed. Alternatives to moving the lens relative to the image sensing surface include changing a shape of the lens.

Abstract: Disclosed is a LMMSE receiver that restores orthogonality of spreading codes in the downlink channel for a spread spectrum signal received over N receive antennas. The FFT-based chip equalizer tap solver reduces the direct matrix inverse of the prior art to the inverse of some submatrices of size N×N with the dimension of the receive antennas, and most efficiently reduces matrix inverses to no larger than 2×2. Complexity is further reduced over a conventional Fast Fourier Transform approach by Hermitian optimization to the inverse of submatrices and tree pruning. For a receiver with N=4 or N=2 with double oversampling, the resulting 4×4 matrices are partitioned into 2×2 block sub-matrices, inverted, and rebuilt into a 4×4 matrix. Common computations are found and repeated computations are eliminated to improve efficiency. Generic design architecture is derived from the special design blocks to eliminate redundancies in complex operations. Optimally, the architecture is parallel and pipelined.
