自适应波束形成器（包括空域谱矩阵的估梯度实现算法、梯度算法、LMS算法、信号子空空间的检测等）(Adaptive beamforming (including the airspace spectral matrix of the estimated gradient algorithm, the gradient algorithm, LMS algorithm, the detection of the signal subspace space, etc.))

Watermarking, as opposed to steganography, has an additional requirement of robustness against possible attacks. An ideal steganographic system would embed a large amount of information perfectly securely, with no visible degradation to the cover object.
