Abstract: Two preferred embodiments provide slot synchronization of an initial cell search. Two Finite Impulse Response (FIR) filters are used to correlate the synchronization codes transmitted in the downlink (forward link). A sign bit is taken after the first FIR to significantly reduce the hardware requirements for the second FIR, and thus the whole system. The correlated results from the second FIR can be further processed using two different algorithms. The first adds a square operation to the correlated results whilst the second takes the magnitude before passing to the next stage. Regardless of which algorithm is adopted, the results are accumulated (I and Q), instead of averaged, and stored in a memory location for each successive correlation over the same location in different slots. The physical-layer processor (PLP) then reads the accumulated results from the memory location and searches for the peak position corresponding to the slot boundary.

Abstract: A processor for enhancing an input luminance signal including: a means for calculating a chroma edge value associated with the input luminance signal; a means for measuring a luminance gradient associated with the input luminance signal; a peaking filter for processing the input luminance signal; a gain adjustment circuit having a gain function that is adjustable relative to the calculated chroma edge value, the gain adjustment circuit being operable to adjust the magnitude of the output of the peaking filter wherein: in a first range of luminance gradients, the output is an attenuated version of the input; in a second range of luminance gradients the output is directly proportional to the input; in a third range of luminance gradients, the output is inversely proportional to the input; wherein said enhanced luminance signal is the sum of the input and output of the peaking filter.

Abstract: The present disclosure provides a very thin semiconductor package including a leadframe with a die-attach pad and a plurality of lead terminals, a die attached to the die-attach pad and electrically connected to the lead terminals via bonding wires, a position member disposed upon the die and/or die-attach pad, and a molding material encapsulating the leadframe, the die, and the position member together to form the semiconductor package. The method for manufacturing a very thin semiconductor package includes disposing a first position member on one side of the die-attach pad of a leadframe, attaching a die onto the opposite side of the die-attach pad, optionally disposing a second position member on top of the die, electrically connecting the die to the lead terminals of the leadframe, and encapsulating the leadframe, the die, and the position member(s) together to form the very thin semiconductor package.

Abstract: A macro-block (MB) quantization reactivity compensation method for a video encoder is provided. The method calculates a reference picture quantization value based on a calculated picture complexity. This predicted reference quantization is combined with the bits-used reactive macro-block reference quantization value to determine the final macro-block reference quantization value. This MB reference quantization value is also made adaptive to the VBV buffer fullness, as well as to the predicted change of the current picture complexity. A video encoder and an article of manufacture that comprises computer readable program code for execution of the method are also provided.

Abstract: The electrical isolation circuit of the present invention has a switch coupled between the DC power source and the electrical application and a comparator for controlling the switch by receiving inputs from the DC power source and the electrical application. The comparator causes the switch to switch ON when the DC power source has a higher voltage than the electrical application allowing the normal operation of the electrical application. However, when the electrical application has a higher voltage than the DC power source, the comparator causes the switch to switch OFF thereby preventing flow of current from the electrical application to the DC power source.

Abstract: A unified filter bank for use in encoding and decoding MPEG-1 audio data, wherein input audio data is encoded into coded audio data and the coded audio data is subsequently decoded into output audio data. The unified filter bank includes a plurality of filters, with each filter of the plurality of filters being a cosine modulation of a prototype filter. The unified filter bank is operational as an analysis filter bank during audio data encoding and as a synthesis filter bank during audio data decoding, wherein the unified filter bank is effective to substantially eliminate the effects of aliasing, phase distortion and amplitude distortion in the output audio data.
