A Short-wave ultra-wideband balanced amplifier with high linearity and lower noise based on balanced structure is presented. The amplifier is realized by Equilibrium structure, Balun broadband matching, Coupler feedback and Power backoff technology. Equilibrium structure is used to greatly improve the second order distortion and Lossless coupler feedback to reduce the noise. The RF frequency is 1...

Artificial signals possess some certain chronological property-the cyclostationarity, with which the traditional DOA estimation can rarely reach the desired precision, or completely turns to be of no avail. Designated for removing the defect, this paper applies the Cyclic-Music algorithm to the MIMO radar's DOA estimation and verifies its effectiveness. Simulations show that the precision of MIMO...
Aimed at the problem of detection of pool edge for aluminum alloy MIG welding, a new method is adopted. The method is used to detect the pool edge of aluminum alloy MIG welding by applying the pulse coupled neural networks algorithm. The pulse coupled neural networks algorithm is introduced in this paper. The detection of pool edge for MIG welding pool is carried out with this algorithm by MATLAB...
Presently the system for recognition of Chinese medical pulse condition mainly aims at single pulse signal; the investigation of compound pulse signal is less. Article mainly researches single pulse signal and compound pulse signal. Firstly, we use wavelet analysis to extract character of pulse signal. Secondly, we make use of the nerve network to recognize. It constructs a considerably practical...
