In this paper at wireless network we use the cognitive radio (CR) channels for communication. The performance of the process is limited by the self-interference which occur in the CR system. To overcome that problem beam forming method is used effectively which reduces the self-interference of smart meter channels. MMSE method is the main concept in the beam forming method utilized in the smart...

Abstract In WCDMA, the interference is produced by different factors such as thermal noise, intra cell traffic, traffic in adjacent cells and external traffic. In addition, the increase in number of users in a cell consequently increases the total interference in the network. Hence, the interference must be controlled to improve the throughput of the network. In this paper, we propose an Interf...

Abstract Ship radiated noise signal is one of the important ways to detect and identify ships, emission interference shield its own a common countermeasure. In this paper, we try use idea enhancement enhance ship with extremely low signal-to-noise ratio, so as achieve anti-explosive interference. We propose deep learning model by mask in temporal domain. Our approach an encoder–decoder structur...

In this study by using noise-free signal estimation the reduction of noise in the image is being proposed. The dyadic stationary wavelet transform is used for both the wiener filter and in estimating the noise free signal. Finding a suitable filter bank and choosing other parameters of the wiener filter with respect to obtained signalto-noise ratio (SNR) is our goal. Testing was being performed...

We study the performance of the minimum-noisevariance beamformer employing a single electromagnetic (EM) vector sensor that is capable of measuring the complete electric and magnetic fields induced by EM signals at one point. Two types of signals are considered: One carries a single message, and the other carries two independent messages simultaneously. The state of polarization of the interfer...
