   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?
   
   Thanks in advance,
   Daryl
