A method and a system for scaling a digital source image consisting of a grid of X by Y pixels into a target image of a different resolution comprises the steps of / tools for:mapping the source pixels onto the target pixels;scaling the source image in the X or Y direction to produce intermediate pixels that are scaled in one direction by determining contributions to each intermediate pixel using a digital filter and accumulating the contributions for each intermediate pixel, wherein each source pixel contributes to one or more intermediate pixels and each intermediate pixel receives contributions from one or more source pixels; and subsequentlyscaling the intermediate pixels in the other direction by determining the contributions to each target pixel using the filter and accumulating the contributions for each target pixel;wherein each intermediate pixel contributes to one or more target pixels and each target pixel receives contributions from one or more intermediate pixels.The method is preferably carried out on a PE array in an SIMD (Simple Instruction Multiple Data) device.

The present invention provides a high-performance adaptive digital receiver with adaptive background control that optimizes the performance in rapidly changing signal environments and provides 3.6 GH; instantaneous bandwidth, SFDR>90 dB, SNR=66 dB, with dynamic digital channelization. The receiver takes advantage of several levels of adaptivity that conventional approaches do not offer. In addition to a dynamic digital channelizer that is adaptively tuned based on detected signals, the present invention employs a powerful software reconfigurable digitizer that is adaptively optimized for the current signal environment to control important receiver parameters such as bandwidth, dynamic range, resolution, and sensitivity.
