    摘要： A mobile telephone able to save power in response to the position of the mobile telephone is disclosed. Location circuitry within the mobile telephone enables the establishment of one or more deep-sleep locations associated with a mobile telephone. When the location circuitry determines that the current location of the mobile telephone is within a selected distance of one of the deep-sleep locations, the mobile telephone operates according to a low power mode of operation wherein only a timer enabling periodic updates of the mobile telephone's position is active. If the location circuitry determines that the mobile telephone is not within a selected distance of one of the predetermined locations, the mobile telephone operates in a standby mode which utilizes more power than the deep-sleep mode but still conserves battery power and enables the mobile telephone to receive calls.

    摘要： Systems for transmitting information symbols utilize ternary codes or pivot codes in conjunction with spread spectrum encoding. The systems comprise at least a first symbol source for supplying an information signal comprising at least a first stream of I,Q bit pairs, means for using either a ternary code or at least one pivot code for spreading the at least first stream of I,Q bit pairs and thereby respectively forming first chips and second chips, and a radio signal modulator for transmitting the first chips and second chips over a radio interface

    摘要： Exemplary embodiments of the present invention comprise a method for compressing data for storage in memory. According to one embodiment, the method forms a set of values based on a monotonically ordered series of look-up table values. For one or more paired values in the set, the exemplary method generates a difference of the values in the pair. After replacing one of the values in the pair with a value based on the differences to modify the set, the exemplary method stores final values based on the modified set in memory. The present invention also comprises memory for storing the look-up table values. One exemplary memory comprises a decoder, an encoder, and one or more patterns of crisscrossed interconnect lines that interconnect the encoder with the decoder. The patterns of crisscrossed interconnection lines may be implemented on one or more planar layers of conductor tracks vertically interleaved with isolating material.

    摘要： The present invention describes a method and apparatus for performing logarithmic arithmetic with real and/or complex numbers represented in a logarithmic format. In one exemplary embodiment, an ALU implements logarithmic arithmetic on complex numbers represented in a logpolar format. According to this embodiment, memory in the ALU stores a look-up table used to determine logarithms of complex numbers, while a processor in the ALU generates an output logarithm based on complex input operands represented in logpolar format using the stored look-up table. In another exemplary embodiment, the ALU performs logarithmic arithmetic on real and complex numbers represented in logarithmic format. In this embodiment, the memory stores two look-up tables, one for determining logarithms of real numbers and one for determining logarithms of complex numbers, while the processor generates an output logarithm based on real or complex input operands represented in logarithmic format using the real or complex look-up tables, respectively.

    摘要： A receiver decodes quantized and unquantized wanted data symbols from received signal samples. The receiver comprises a control adapted to process a group of currently received signal samples to determine a corresponding current set of unquantized wanted data symbols and an interfering waveform representative of a sum of other unwanted data symbols by subtracting an amount of a previously decoded set of quantized wanted symbols and a previously determined interfering waveform. A quantizer quantizes the determined current set of unquantized wanted symbols to obtain corresponding quantized symbols.
