Researches on target detection are mainly focus on the amplitude characteristics nowadays. Sometimes the only use of amplitude characteristics is not enough to describe the signal, so that the target detection performance is usually poor. In this essay a method to make use of the information “hidden” in the signal phase is put forward, the theory is based on polynomial fitting of the signal phase...
The recovery can be achieved from the undersampling signal in compressed sensing theory relying on the sparsity and incoherent characteristics of the signal. A data compression algorithm is advanced in this article, based on compressed sensing and wavelet transform. Firstly the framework of the compressed sensing theory is introduced, and then a one-dimension and a two-dimension wavelet transform...
Because of the unique characteristics of Single-Chip Microcomputer, some students find it is very hard to learn it well at the first sight. Especially the materials and books used nowadays are often focusing too much on the structure, system and function of the Micro-Controller Unit (MCU for short). However, there exists an extremely shortage on the experiment content and technique. Some suggestions...
