	· The Viterbi algorithm in Mathcad. It contains two versions: one in which data structures are proportional to packet size, and one with ring buffer implementations, suitable for packets of any size. [mcd]
	· Simulation of a delay diversity space-time code in Mathcad. Arbitrary number of antennas, imperfect channel state estimation, Viterbi detection. [mcd]
	Update selected sections of Mobile Channel Characteristics when they become available. For the Mathcad version, just right-click on the link for the desired section, and choose "Save Link As" or "Save Target As". When the "Save As" window appears, select the folder that contains Mobile Channel Characteristics (for example, c:\Program Files\Mathsoft\Handbook\mobchann) and overwrite the old copy of the mcd file. For the HTML version, right-click and save the zip file, then unzip it into the folder you created for the text (if you have forgotten where it is, search for channelhome.htm).
