We studied the efficient, simultaneous communication of many users/devices sharing a common frequency spectrum. Modern radio communication relies on assigning unique signals to users. Short signals allow efficient transmission. Large sets of signals allow many users at once. Sets of signals with low cross-correlation minimize interference among transmissions. Our work was to better describe the tradeoff among these goals. For a given signal length, we found a bound on the size of signal sets which are interference-optimal according to the Welch Bound, and for large sets we found a tighter bound on interference.
