A sparse planar array vertically placed in y–z plane is proposed to improve the angle estimation accuracy of sources in low angle region with reflection multipath. With two sizes of spatial invariances along both dimensions, the array estimates the azimuth and elevation angles using unitary ESPRIT (estimation of signal parameters via rotational invariance(More)
Image compression has been a long-term focus in the image processing field, which plays an important role in improving the image performance in complex system. This paper aims at addressing an important issue in the design of image compression algorithm, which is the bit rate real-time control strategy for image. To cope with this problem, this paper(More)
