An interference suppressing OFDM system for ultra wide bandwidth radio channels
The orthogonal frequency division multiplexing (OFDM) technique introduced here, termed interference suppressing OFDM (IS-OFDM), is a point-to-point physical link system for ultra wide bandwidth (UWB) radio channels which has the capability of suppressing narrow-band interference. System performance evaluation has been provided in the presence of narrow band interference, inter-symbol/inter-channel interference, or frequency selective fading. BER performance of the IS-OFDM is compared with an equivalent ordinary OFDM system. As shown, the IS-OFDM in a narrow band interference channel has a significant advantage over the ordinary OFDM which exhibits an error floor for every narrow band interference to signal ratio. Also, in an UWB indoor multipath channel the IS-OFDM has a significant advantage over the ordinary OFDM which, as shown, does not offer an acceptable performance for this type of channel.
