ABSTRACT:
A method for operating an IS-OFDM system for point-to-point wireless communications that suppresses narrow-band interference comprises the steps of producing and transmitting an IS-OFDM signal including the use of parallel-to-serial converters in order to maintain the same data rate for the transmission as the input data rate. The method further comprises the steps of receiving and recovering an IS-OFDM signal.
