摘要： Improving the reliability of digital radio communication affected by multi-path interference under an environment where there are multiple objects that scatter electromagnetic waves is accomplished. A wireless transmitter transmits a first transmission wave having a first carrier frequency (f0+Δf), modulated by a modulator with an information signal having a frequency band f1 which is predetermined, from a transmitting antenna, and transmits a second transmission wave having a second carrier frequency (f0−Δf), modulated by a modulator with such information signal. An average frequency f0 between the first carrier frequency (f0+Δf) and the second carrier frequency (f0−Δf) is kept constant, whereas the first carrier frequency (f0+Δf) and the second carrier frequency (f0−Δf) are varied by controlling a frequency difference Δf to vary.

摘要： A wireless transmitter has a modulator modulating an information signal of a frequency f1 by a carrier wave of a frequency f2 to output a first modulated signal, a transmitting antenna transmitting the first modulated signal using a linearly polarized wave, and a motor rotating the transmitting antenna at a frequency f3 to rotate the outgoing linearly polarized wave at the frequency f3 thereby multiplexing the first modulated signal with a linearly polarized wave component and a horizontally polarized wave component, the two components being independent of each other. A wireless receiver has diversity receiving antennas receiving the signal on a plurality of polarization planes to obtain a plurality of input signals; a path difference phase shifter compensating each of the input signals for the phase shift stemming from path differences, and a composer composing the corrected received signals.
