A configurable transmitter for a wireless communication system may include a flexible block coder, an IFFT block, an analog and RF block, and an antenna coupled in series. The flexible block coder may advantageously perform forward error correction and mapping of a data stream to generate a processed data vector. To perform these functions, the flexible block coder may include a data formatter and a multiplier. The data formatter may format the data stream into an output vector, whereas the multiplier may multiply the output vector by a configurable channel coding matrix to generate the processed data vector. The size of the output vector may be a reflection legacy compatibility and data rate. The size of the processed data vector is equal to a product of the output vector and an inverse of a coding rate. The channel coding matrix may be compressed.

A method provides for an improved chroma-key suppression technique. The improved method reduces a halo-like effect which might otherwise appear in a composite image containing a foreground object selected from a first image and a background image selected from a second image. In accordance with the present invention, a chroma-key patch is translated into x, y axis coordinates and one or more pixels of the image in question can be compared to a chroma-key patch and a transition region at least partially surrounding the chroma-key patch to better select suppression signals to be applied in an image processing operation.
