Abstract of Presentation
In this seminar are discussed information acquisition, processing, transmission systems and their development trends. Current data acquisition systems can provide whole spectrum of the practically required solutions. Processing speed of available state of art distributed supercomputers can reach to the multiple TFlops, which is quite high, but probably will never be enough for computer simulations and realistic models construction. Due to the distributed structure of high speed data processing systems the communication between their modules can become the bottleneck and will create the strict processing speed limit. Optical fiber based data networks could solve the communication problems by means of the DWDM with up to the 1-1.5Tbps data rate, but in case of the optical networks limitations come from the access control and add/drop multiplexing elements speed. Wireless systems distribute the medium access control and allow users mobility. The two main problems of wireless systems are multi-path propagation and the time varying nature of channels. Multi-path fading and time-varying channel problems can be solved by means of the pre-equalization, which requires the prediction of the channel response. Neural networks can be employed for learning of stationary time varying channels, but they are not applicable in the general case due to the limited training data. As the reasonable solution of the problem can serve evolutionary and genetic algorithms, which are optimal search techniques in multidimensional space and are based on the principles of natural evolution.
