METHOD AND APPARATUS FOR REDUCING PROBABILITY OF DETECTION, IMPROVING JAMMING RESISTANCE AND SECURITY FOR BROADBAND WIRELESS SYSTEMS

摘要

Systems and methods for generating OFDM signals are provided in which sub-carrier usage is selected and/or remapped in various manners. For example, in some embodiments remapping using a security sequence is employed; in other embodiments, decoy sub-carriers are employed; in other embodiments, mask sub-carriers are used to cover jammed portions of a channel.
