本发明公开了一种非线性放大三维信号调制解调方法及装置。该方法利用无线传输系统实现具有斯托克斯约束的三维调制，发射端由三维调制产生的两路信号分别独立正交通过工作在非线性放大的功率放大器和天线进行信号发射。接收端通过极化正交的天线或单天线获取存在非线性畸变的接收信号。利用两路调制符号的斯托克斯约束关系，对接收信号幅度和相位的非线性畸变进行估计和补偿。本发明可应用于单载波频域均衡无线传输系统，利用具有斯托克斯约束的三维调制进行信息传输。即使功率放大器工作在非线性区甚至于饱和放大区，所提方法使得无线接收机仍然实现高性能接收，从而显著提升无线通信系统的功率效率。 The invention discloses a nonlinear amplification three-dimensional signal modulation and demodulation method and device. According to the method, three-dimensional modulation with Stokes constraint is realized by using a wireless transmission system, and two paths of signals generated by the three-dimensional modulation at a transmitting end independently and orthogonally pass through a power amplifier and an antenna which work in a non-linear amplification state to perform signal transmission. And a receiving end obtains a receiving signal with nonlinear distortion through a polarized orthogonal antenna or a single antenna. And estimating and compensating nonlinear distortion of the amplitude and the phase of the received signal by
