I ahve a list of transmission start times and a known transmission length. I want to finc out how many of the transmissions overlap one another. Can anyone think of a quick way to do this. Brute force is very slow. By brute force I mean comparing the start time of each start time to evry other start time to see if they are within the transmission time. I've been trying to figure out a MMA algorithm that would be analogous to plotting all of the transmit times and counting the overlaps but I'm not sure how to do this. Any suggestions?
