Walt, YOu should know that Walsh codes are only orthogonal if they are synchronous. the probolem is that the system assumptions break down when you got asynch Walsh codes. If you do not maintain the orthgonality of the channels, then the users interfere with each other, hence they are not "white noise" to each other. Kind of like RF spurious being emitted all over the place, but in the digital domain.
