On Wednesday, July 29th, IEEE Xplore will undergo scheduled maintenance from 7:00-9:00 AM ET (11:00-13:00 UTC). During this time there may be intermittent impact on performance. We apologize for any inconvenience.
Inefficient spectrum usage was historically acceptable because receiver complexity and cost could be minimized. Today, new demands for RF spectrum, especially to accommodate new broadband wireless services, require a change in the design philosophy of consumer receivers due to ever increasing interference in our limited RF spectrum.
