[Discuss-gnuradio] inconsistency in the PER versus distance using USRP

2008-11-20 Thread Bill Stevenson
Hello, everybody! I am using two USRP to find the average PER at a certain distance, but the average PER at a certain distance seems to be varying every day. Yesterday, the PER was around 5% when two usprs were 10 feet apart, but today the PER was around 2.5%  which has been diminished by 50%!
