Briefly, in accordance with one embodiment of the invention, an orthogonal frequency division multiplexing system may provide a dynamically calculated cyclic extension, the length of which may be based at least in part on a delay spread due to an experienced environmental condition. The method also includes removing the repair material from the solder material, and reflowing the solder material. After storing the raster state information, the one or more primitives of a second context are rasterized.
