Examples
- The problem of joint estimating the frequencies and time - delay of multiple sinusoids received at two separated sensors is considered . the frequencies are firstly estimated using a state - space realization approach . the tune - delay is then found using a direct - form esprit - like method . finally , the performance of the proposed algorithm is demonstrated via computer simulations using sinusoidals as well as real speech data
6 .在第七章提出了一种基于状态空间实现的频率、时延联合估计算法，正弦波的频率首先用状态过渡矩阵的特征值估计得到，然后时延由估计的频率和观测矩阵直接给出。 - Based on fourth - order cumulant , a computationally efficient method for joint estimating both directions of arrival and ranges of near field sources with known carrier frequency is firstly presented . the proposed algorithm need not any spectral peak searching and the 2 - d parameters are automatically paired . lt is suitable for arbitrary additive gaussian noise environment . in the following section , a 3 - d esprit method for jointly estimating of frequencies , doa ' s and ranges of multiple near - field sources with unknown carrier frequencies is proposed . the parameters estimation are given by the eigenvalues of different matrices . furthermore , its performances are confirmed by several computer simulations
利用四阶累积量，第五章首先给出了一种载频已知的情况下基于近场源的距离和波达方向联合估计算法，通过构造的阵列输出信号四阶累量矩阵使空间信号到达方向和距离估计无需谱峰搜索，且参数自动配对，适合于任意高斯噪声环境。进一步在第三节提出了一种载频未知的情况下的多个近场窄带信号源doa 、距离和频率联合估计的3 - desprit算法。
