    摘要: A method and apparatus for performing packet processing is described. A signal having a preamble sequence is received. A detection parameter estimate is derived from the preamble sequence. The detection parameter estimate is evaluated to process at least one packet in the signal.

    摘要: A photographic display apparatus which comprises a substrate, as for example, a glass sheet having a mirrored surface thereon. An orthochromatic, high contrast, graphic arts copy film, or so-called "ortho film," having a positive visual image is disposed on the substrate and is covered by a transparent sheet. These three components may then be secured together by conventional means. The image on the ortho film is viewed through the transparent sheet against the mirrored surface of the substrate and which presents a unique visual appearance, similar to that of an image etched onto glass. The ortho film may be made by using a positive print of the desired image and generating a negative film therefrom through conventional photographic techniques. This negative film may be printed and enlarged if desired during the printing process in order to produce a positive ortho film sheet which is used in the above photographic display apparatus.
