中文说明： 基于负熵最大的独立分量分析，信号处理中的旋转不变子空间法，是国外的成品模型，是路径规划的实用方法，供做算法研究人员参考，构成不同频率的调制信号。
English Description：
Based on the maximum negative entropy independent component analysis, the rotation invariant subspace method in signal processing is a foreign finished product model and a practical method of path planning, which can be used as a reference for algorithm researchers to form modulated signals with different frequencies.
