Waveform set with low-range sidelobes plays an important role in multiple-input and multiple-output (MIMO) radar. In this paper, the linear frequency modulation and phase-coded (LFM-PC) waveform including its properties is analytically presented. Furthermore, a Frank code set with zero sidelobe zones is proposed in the pursuit of low peak sidelobes, while the processing method is proposed to compress...
According to underwater terrain characteristic, the multi-index synthetic evaluation theory is used for calculating matching area of an underwater terrain-aided navigation system in this paper. Considering the terrain elevation standard deviation, roughness, terrain correlation coefficient, topographic information entropy and other crucial terrain characteristic parameters on the effect of navigation...
As is well known, face recognition under varying illumination conditions remains one of the most challenging tasks. How to achieve illumination invariant features is the key issue of face recognition. This paper provides a novel face recognition method using mirror-like Gabor features (MGF). The paper first presents the process of even/odd MGF extraction. It then demonstrates that the even MGF are...
In this paper, a novel sequence detection method based on codebook with channel correlation information (CCI) for the reliable feedback of CQI (channel quality information) in the uplink fast feedback channel is proposed, which utilizes the codebook based maximum likelihood detection method. Using the relatively less training frames, we can get an accurate approximation of the statistical CCI for...
In this paper, a cross fourth order moment minimum norm approach is proposed to achieve multi-path chirp time delay estimation. Because chirp signals are nonstationary, we define a special time-varying cross fourth order moment. Using this time-varying fourth order moment, the time delay estimation of the nonstationary chirp signals is converted into the parameter estimation of stationary signals...
