This paper describes a new modulation technique known as frequency domain reciprocal modulation (FDRM) that has a characteristic of high immunity to dynamic multipath distortion. FDRM is a multicarrier transmission technology that is related to orthogonal frequency division multiplexing (OFDM). FDRM uses frequency domain reciprocal harmonic carriers to allow automatic cancellation of all linear...
