To solve the problem of channel with distortions, an adaptive circuit is configured by a new laddered method based on relevant articles, and simulation study was made on four dimensional Chua's chaos oscillator. The simulation results demonstrated that: synchronization of two chaotic oscillators can be achieved when adaptive circuit has adaptive capability. Synchronization of two chaotic oscillators cannot be achieved when adaptive circuit has no adaptive capability. Simulation studies were done for five scroll chaotic oscillators that achieve bond-orbit, coupling and pulse synchronization.

为了解决信道畸变问题，根据相关文献提出的梯度法，本文构造了一种自适应同步电路，并以四阶变型蔡氏混沌振荡电路为例进行仿真研究，仿真结果表明：当自适应同步电路具有自适应效应时能实现有噪声干扰情况下的两个混沌振荡电路的同步；若自适应同步电路没有自适应效应时，则不能使两个混沌振荡电路同步；以5涡卷混沌振荡电路为例用键波同步法、耦合同步法、脉冲同步法进行同步仿真研究。
