| 摘 要： | 为同时改善不对称的随机极性甚小幅相(ARP-VMAP)调制信号的频谱利用率和能量利用率，提出了一种多元位置3值VMAP调制方式，设计了基于BP神经网络或支持向量机解调器的接收机。对比和分析了ARP-VMAP调制、3值VMAP调制、多元位置ARP-VMAP调制和多元位置3值VMAP调制信号的功率谱特性、?60 dB带宽、频谱利用率和解调性能。仿真结果表明，新的调制方式不仅提高了频谱利用率，而且显著改善了解调性能。

| Abstract: | In order to improve the spectral efficiency and energy efficiency of asymmetry, random-polar and very minimum amplitude and phase (ARP-VMAP) modulated signal simultaneously, an M-ary position and three-valued VMAP modulation was presented, and the receiver based on BP neural network or support vector machine demodulator was also designed. The contrast and analysis of the power spectrum, the ?60 dB bandwidth, the spectral efficiency, and the demodulation performance among modulations as the ARP-VMAP, the three-valued VMAP, the M-ary position ARP-VMAP, and the M-ary position and three-valued VMAP, were carried out. Simulation results show that the new modem not only raise spectral efficiency, but also improve demodulation performance significantly. |
