通过观测获得的AR序列
常常由于混有观测噪声而使AR谱估计的分辨率和估计质量大大下降。本文通过构造高阶相关阵
用householder变换递推算法做AR谱估计
得到了AR参数的无偏估计
从而剔除了噪声对AR谱的污染
保证了较好的估计质量。
AR series obtained by observation
as they are mixed with observated noise
often reduce greatly both the resolution and the estimating performance of AR spectral estimation. The recursive algorithm of Householder transform is applied for AR spectral estimation by forming the high-order autocorrelation matrix
and an unbiased estimation of AR parameters is obtained. Thus
the noise pollution to AR spectral is overcome and a better estimation performance is ensured.
