Abstract

This paper proposes a closed-form estimation technique for a wideband constant amplitude polynomial-phase signal embedded in white Gaussian noise. It is shown that it is possible to jointly estimate the highest order phase coefficient and direction of arrivals of the signal through a closed-form method. Hence it is, computationally, much simpler than maximum likelihood method which involves highly non-linear multidimensional optimization. Simulation and comparative results are included to show its effectiveness.

传感器阵列宽带多项式相位参数估计

针对嵌入高斯白噪声中的宽带等幅多项式相位信号，提出了一种闭式估计技术。结果表明，通过封闭形式的方法可以联合估计信号的最高阶相位系数和到达方向。因此，在计算上，它比涉及高度非线性多维优化的最大似然法简单得多。仿真和对比结果表明了该方法的有效性。
