How does a MB-OFDM based system protect itself from in-band destructive interference?
MB-OFDM system has several mechanisms to withstand harmful interference to its operation. One of the methods may simply be turning off the tones affected from such signals. In addition, the MB-OFDM system provides various redundancies such as distributing the transmitted data over several other tones, interleaving and scrambling and the use of forward error correction methods. Thus, even if several tones are subject to narrow-band interference, the impact on the receiver packet error rate may be negligible.
