摘要
对一种用旋转不变技术估计信号参数的新方法(EEPRIT)进行理论分析和算法研究。主要研究了R.H.Roy等提出的新算法,该算法最大的优点是不要求噪声场为空间白和不需要求解奇异对的广义特征值。最后,对文献[2]、[3]和[6]提出的三种算法进行了计算机模拟。结果表明,R.H.Roy等提出的算法具有很大的优越性。
A new approach to Estimation of Signal Parameters by Rotational Invariance Techniques (ESPRIT) is analysed. The main work is to research a new algorithm given by R. H. Roy, etc. The biggest advantage of this algorithm is that the noise doesn't have to be space white noise and doesn't have to solve the generalized eigenvalues of singular matrix pairs.The computer simulations were done with the algorithm of paper [2],[3],[6]. The simulation results show that the algorithm of R. H. Roy is advanced.
