| Abstract: | Based on vector antenna,a novel approach to the three-dimensional joint modulation of the phase,polarization amplitude,and polarization angle parameters of an electromagnetic signal is presented.Its implementation strategy is also given while the proposed three-dimensional joint modulation constellations and the constellation point distributions are discussed.The calculation method of the bit error rate(BER) of the proposed three-dimensional joint modulator and demodulator is also given.Both the analysis and the simulation results show that a high information transmission rate can be kept while a low bit error rate is obtained by the proposed method. |

| Keywords: | vector antenna three-dimensional modulation three-dimensional constellation BER |
