Title: Method of evaluating fiber pmd using polarization optical time domain recflectometry
Inventor: CHEN XIN
IPC: H04B10/00
Filed: 2003-10-28
Abstract: A method for screening fiber polarization mode dispersion using a polarization optical time domain reflectometer. A pulse radiation is emitted into the fiber under test, and the backscattered radiation is measured by the POTDR and used to obtain a POTDR trace. The POTDR trace is then analyzed to compare the variation of signals along the length of the fiber, the variation in signals relating to the level of PMD along the length of the fiber. Because high levels of PMD correspond to localized levels of low variability, by setting the variability of signal threshold sufficiently low, fibers having unacceptably high localized PMD can be identified and removed.

Title: Low complexity equalizer for radio receiver
Inventor: DILOISY ROMAIN
IPC: H04B1/707
Filed: 2003-11-14
Abstract: A diversity receiver (60) has two diverse channels fed by the antennas, an adaptive equalizer (20,30) for each channel and a coefficient adapter (40) for adapting two sets of coefficients in a time shared manner for the equalizers. A combiner combines the equalized signals. By sharing one adapter for adapting the coefficients between two or more equalizers, the calculation load can be reduced. This is useful for small mobile terminals powered by battery, for use with GSM or UMTS or other radio networks. It can be applied to any type of equalizer, and using any manner of time sharing. The combiner can exploit any type of diversity between the equalized signals. The equalizers can output two equalized signal values in consecutive time slots, by reusing the same coefficients, while new coefficients are being calculated.

Title: Error detection and recovery within processing stages of an integrated circuit
Inventor: FLAUTNER KRISZTIAN
IPC: G06F1/32
Filed: 2004-02-26
Abstract: An integrated circuit includes a plurality of processing stages each including processing logic (2), a non- delayed latch (4), a delayed latch (8) and a comparator (6). The non- delayed latch (4) captures an output from the processing logic (2) at a non-delayed capture time. At a later delayed capture time, the delayed latch (8) also captures a value from the processing logic (2). The comparator (6) compares these values and if they are not equal this indicates that the non-delayed value was captured too soon and should be replaced by the delayed value. The non-delayed value is passed to the subsequent processing stage immediately following its capture and accordingly error recovery mechanisms are used to suppress the erroneous processing which has occurred by the subsequent processing stages, such as gating the clock and allowing the correct signal values to propagate through the subsequent processing logic before restarting the clock. The operating parameters of the integrated circuit, such as the clock frequency, the operating voltage, the body biased voltage, temperature and the like are adjusted so as to maintain a finite non-zero error rate in a manner that increases overall performance.
