A variable-width memory may comprise multiple memory banks from which data may be selectively read in such a way that overall memory access requirements may be reduced, which may result in associated reduction in power consumption.

Embodiments of an adaptive in-phase (I) and/or quadrature-phase (Q) imbalance correction for multicarrier wireless communication systems is generally described.

Adaptive IQ imbalance correction for multicarrier wireless communication systems

An in-phase and guadrature (IQ) imbalance error-correction method includes estimating, on the basis of a constellation error in a received orthogonal frequency division multiplexing (OFDM) signal, an extent of an I/Q imbalance error, caused by direct IQ conversion of the received OFDM signal. On the basis of that extent, an equalizing transformation that reduces that error is estimated.

A method for displaying grey-scale images at a desired grey scale resolution up to the visible limit on a display having a matrix of pixels, includes the steps of: defining a plurality of control matrices, each of said control matrices having a size and equal to the desired grey scale resolution of the display, each position in each of said control matrices corresponding to a specific pixel of said display; defining a super matrix, each position in said super matrix corresponding to one of said plurality of control matrices and having an assigned number in a range equal to the desired grey scale resolution; turning on a selected number of pixels within each of said control matrices based upon the grey scale value of the pixel, the orientation of the pixels turned on based on the value of a circular queue of size equal to said desired gray scale resolution; and adjusting the starting value of said circular queue for each of said control matrices based upon the number contained in the position of the super matrix corresponding to each control matrix and the gray scale value of the incoming pixel.

A method for displaying grey-scale images at a desired grey scale resolution on a display having a matrix of pixels, comprises the steps of: defining a control matrix having a size smaller than the entire display and equal to the desired grey scale resolution of the display, each position in the control matrix having an address assigned such that unintended artifacts in the display are controlled; horizontally and vertically mapping the control matrix into the display such that each pixel in the matrix of pixels in the display corresponds to an address in a control matrix mapped into the display; comparing control matrix address of each pixel in a frame of an image to be displayed on the display to a range of address values and turning that pixel on if the grey scale value of that pixel is within the range of address values, the range of address values arranged in a circular queue and being equal to the grey scale value of that pixel; and shifting the range of address values in the circular queue for successive frame by an amount equal to the grey scale value of the pixel to be displayed.
