摘要 定义了频率估计和信号到来角估计的信号模型,介绍了基于小波包理论的频率估计,推导了两者的等价性和分辨率的关系,仿真结果验证了频率和DOA估计的一致性。 Models of frequency estimation and DOA (Direction-of-arrival) estimation are defined respectively. Wavelet packet-based frequency estimation is introduced. Equivalence of frequency and DOA estimation, and relationships of resolution between them are investigated. Consistency of them is validated by the simulation results.
