基于Teager-Kaiser算子的改进波束域MUSIC时延估计算法
An improved beam-space MUSIC time delay estimation algorithm based on TK operator
摘要
Abstract
In order to reduce the calculated quantity and improve the function of noise of beam-space multiple signal classification (MUSIC)time delay estimation, an improved algorithm has been presented in this paper. According to the sensitive characteristics of the data's instantaneous change, Teager-Kaiser(TK)operator processes the correlation function of the received and reference signal. Then the beam-space transformation matrix and the beam-space output data can be estimated from the processing result. After that, the paper estimates the time of arrival(TOA) with MUSIC algorithm. Stimulation results show that this method was better than the beam-space MUSIC time delay algorithm. The performance of high-resolution estimate has been improved.关键词
