  • Patent number: 8978000
    Abstract: The present disclosure relates to an arrangement and a method of performance-aware buffer zone placement for a high-density array of unit cells. A first feature density of the array is measured and maximum variation for a parameter within a unit cell is determined. A look-up table of silicon data is consulted to predict a buffer zone width and gradient value that achieves a variation that is less than the maximum variation for the unit cell. The look-up table contains a suite of silicon test cases of various array and buffer zone geometries, wherein variation of the parameter within a respective test structure is measured and cataloged for the various buffer zone geometries, and is also extrapolated from the suite of silicon test cases. A buffer zone is placed at the border of the array with a width that is less than or equal to the buffer zone width.

  • Patent number: 6775318
    Abstract: The present invention provides an apparatus and method for code group identification and frame synchronization for cell searching used in wide-band DS-CDMA cellular systems. This method characterizes each secondary synchronization code sequence (SSCS) with a corresponding theoretical frequency sequence, which represents the occurrence times of CS1 to CS16 in a corresponding SSCS. Thus, 64 secondary synchronization code sequences corresponding to 64 code groups defined in DS-CDMA systems also corresponds to 64 theoretical frequency sequences. By characterizing the SSCS transmitted by a base station, a real frequency sequence can be generated. Comparing the real frequency sequence with the 64 theoretical frequency sequences, one can determine one or two candidate code groups, which may be employed by the base station.
