摘要
提出了一种基于自适应ＡＲ过程多数求解而进行谱估计的神经网络方法。采用神经网络完成的ＡＲ参数估计回避了以往各种算法中的递推公式计算，实现了无乘法器的求解。该神经网络模型结构简单，便于硬件实现。计算机模拟结果表明，这种方法对平稳和非平稳随机过程进行的ＡＲ／ＭＥ谱分析结果令人满意。
A neural network for evaluating spectrum based on the solving AR(adaptive reccerent)parameters is proposed in this paper.By using the neural network,not only the evalua-tion of the AR parameters are performed and avoid recurrently computed as foregoing variant algo-rithm,but also it can be solved not employing multipliers. The architecture of this neural network is relatively simple,and easily implemented by the hardware.Computer simulation results show that the spectrum analysis of AR/ME for stationary and non-stationary process is satisfactory.
