摘要： A method for automatic prevention of vertical streaks involves processing output signals from a plurality of photosites to determine what gain is appropriate for each output signal. An exemplary preferred method distinguishes between different types of output signals for which a first type of gain is appropriate and other output signals for which a second type of gain is appropriate. The first type of gain is a proportionate gain. The second type of gain is determined from at least one gain which is appropriate for output signals generated by neighbor photosites. The second type of gain is applied to the output signals when the processing indicates that a light-absorbing optical obstruction associated with the photosites generating the output signals appears to be positioned in an optical path of the photosites on or between a scan surface area over which an object to be imaged by the photosites is positioned and a calibration strip facing the scan area surface.

摘要： A method for automatic removal of vertical streaks involves a comparison between image data for a pixel and its neighbor pixels to determine whether the pixel is non-homogenous. In a preferred method, the comparison employs an adaptive threshold against which a difference between the pixel and its neighbor pixels is compared, with the adaptive threshold taking into account accumulative information pertaining to pixels generated by a common optical sensor element. A preferred method also includes the step of considering locations of non-homogenous pixels in the image to determine whether the image data associated with the non-homogenous pixels needs to be changed or modified. A preferred method also includes the step of associating the non-homogenous pixels with different image data.

摘要： Techniques are provided to pre-distort a signal that is transmitted by a transmitter of a wireless communication device, e.g., a device configured for wireless radio frequency communication. The transmitter of the device inherently introduces distortion to the baseband signal to be transmitted. In at least one frame of a baseband signal to be transmitted, at least one subcarrier in a preamble of the frame is shifted in frequency such that the at least one subcarrier is offset from a normal subcarrier frequency position. The at least one frame of the baseband signal is supplied to the transmitter that is configured to produce a transmit signal for transmission. The transmit signal at an output of the transmitter is sampled or detected and inter-modulation distortion in the transmit signal is determined at one or more frequencies as a result of shifting of the frequency of the at least one subcarrier in the preamble of the at least one frame. The baseband signal is pre-distorted based on the inter-modulation distortion prior to coupling to the transmitter for transmission.

摘要： The present invention discloses a low-complexity estimation method for obtaining a weighting vector for an antenna system with adaptive phased arrays. A first matrix is generated from a plurality of statistically independent symbols of the receiving signals. The plurality of statistically independent symbols is received from two or more antennas over some period of time without a prior knowledge of the properties of the symbols. A second matrix, which is the covariance matrix of the first matrix, is calculated. Subsequently, a column or row is selected from the second matrix to be the weighting vector for two or more antennas in an adaptive phased array antenna system.
