    摘要: A method for reducing current drain in a communication device includes a first step of detecting interference including intermodulation and crossmodulation products. A next step includes determining a frequency offset of the interference with reference to the operating receiver band. A next step includes measuring a power level of the interference. A next step includes calculating a receiver linearity required to achieve a desired signal-to-interference ratio. A next step includes adjusting the receiver linearity in order to achieve the desired signal-to-interference ratio. Optionally, the receiver dynamic range can be adjusted to suit the reduced signal swing due to the reduced linearity.

    摘要: Apparatus and method for correlating a received communication of a known sequence over a wireless channel. Processing at the required higher sampling rate is achieved through the use of a finite impulse response (FIR) filter (24) having a small number of taps for interpolating samples. This reduces hardware requirement by as much as one-half that of conventional techniques based on over-sampling the received signal, while obtaining amplitude degradation which is no worse than experienced when employing conventional techniques.

    摘要: A proposed data processing device includes at least two processor units, which each is adapted to process digitized precorrelation navigation satellite signal data as well as to process alternative data and/or signals relating to at least one function being uncorrelated with the satellite signal data. The device includes at least one data buffer adapted to store data sets, where each set includes a number of instances of the satellite signal data. A control module in the device controls execution of a processing job with respect to a stored data set by allocating individual processing tasks to at least one of the at least two processor units based on a current processing load on each processor unit.

    摘要: A method and apparatus for performing a power efficient cell search in a multi-cell wireless communication system are disclosed. A wireless transmit/receive unit (WTRU) having a memory that stores a cell identification list of prioritized previously top-ranked cell identities (IDs) is used to perform the cell search. A primary synchronization code (PSC) correlation peak location on a received signal is selected. A common pilot channel (CPICH) correlation value is determined by non-coherent integration of a local signal created based on a first cell ID on the cell identification list to the received signal. If the CPICH correlation value is greater than a noise threshold, thus indicating that the first cell ID is a newly found cell ID, or if a last cell ID in the cell identification list is reached, an additional determination is made as to whether there is more than one cell ID on the list having the same timing.

    摘要: This device (10) is suitable for receiving a baseband spread spectrum analogue signal (r(t)) emanating from a multipath propagation channel, this analogue signal conveying symbols. It comprises a structure with at least two stages (130, 140, 150), each stage comprising a block for estimating said symbols, and, with the exception of the last stage (150), a block for regenerating interference using the symbols estimated by the symbol estimating block of the said stage. The signals are transmitted at the chip rate from one stage to the other and each of the interference regenerating blocks uses a complete Nyquist formatting.
