JOINT CHANNEL ESTIMATION, DATA DECODING, AND GROUP-SPARSE IMPULSIVE NOISE ESTIMATION FOR SLOWLY TIME-VARYING SINGLE COPYRIGHT UNDERWATER ACOUSTIC COMMUNICATIONS

The Gaussian noise assumption is usually made for slowly time-varying underwater acoustic communication (UWAC) systems, which is entirely adequate for most cases.However, certain human activities such as geophysical surveys, multi-beam echosounders and iceberg PR783 breakup generate impulsive noise.Consequently, the impulsive noise degrades the des

The reaction behaviour of partially reduced iron (PRI) was studied to understand the effect of PRI utilisation in the blast furnace process.For quantitative analysis, the reaction behaviour of PRI under typical operating conditions of a Probiotics blast furnace was measured using the thermogravimetric method along with the reduction behaviour of he

Textureless and geometric discontinuities are major problems in state-of-the-art dense image matching methods, as they can cause visually significant noise and the loss of sharp features.Binary census transform is one of the best matching cost methods but Horse Bit Accessories in textureless areas, where the intensity values are similar, it suffers

Research interest regarding maqui (Aristotelia chilensis) has increased over the last years due to its potential health benefits as one of the most antioxidant-rich berries.Ultrasound-assisted extraction (UAE) is an advanced green, fast, and ecological extraction technique for the production of high quality configuration plate extracts from natural

As Russian economy is still largely oriented on commodities production, there are a configuration plate lot of cities where mining and commodity-oriented enterprises are the backbone of city economy.The mentioned enterprises mostly define the life quality of citizens in such cities, thus there are high requirements for engineering of city-forming e
