信号频率测量在雷达信号处理巾起到重要的作用。基于DFT和自相关理论,该文提出了一种双正弦信号频率的快速估计方法。该方法先用DFT估计其巾一个频率及其幅度,以此频率对信号解调并对消该频率成分,最后利用自相关理论估计信号的频差。计算机模拟证实了方法具有精度高、测频速率快的特点。

This paper is concerned with robuslness with respect to small delays for the exponential siability of abstract differential equations in Banach spaces. Some necessary and sufficient conditions are given in terms of the uniformly square integrability of the fundamencal operator family and the uniform boundedness of its resolvent on the imaginary axis.

【期刊论文】A NOVEL METHOD FOR SIGNAL PARAMETERS ESTIMATION

Based on uniform circular array and its element output signal delay, a novel method for estimation of spatial frequency, azimuth and elevation is presented. Without any spectral peak search and parameters pairing, the resulting method is computationally efficient with high resolution and small variance, even in short data length. Computer simulation demonstrates the effectiveness of this method.

In this paper, a new observation equation of non-Gaussian frequency selective fading Bell Labs layered space time (BLAST) architecture system is proposed, which is used for frequency selective fading channels and non-Gaussian noise in an application environment of BLAST system. With othogonal matrix triangularization (QR decomposition) of the channel matrix, the static observation equation of frequency selective fading BLAST system is transformed into a dynamic state space model, and then the particle filter is used for space-time layered detection. Making the full use of the finite alphabet of the digital modulation communication signal, the optimal proposal distribution can be chosen to produce particle and update the weight. Incorporated with current method of reducing error propagation, a new space-time layered detection algorithm is proposed. Simulation result shows the validity of the proposed algorithm.
