ISSUES OF TRANSMITTING INFORMATION VIA COMMUNICATION SYSTEMS

This article discusses the problems of data transmission through communication systems, such as:  signal attenuation, shadow zones, multipath propagation of signals, signal fading.  The characteristic features of signals transmitted through the connecting channels are highlighted and described. Such systems are affected as:  MIMO technologies — a method of spatial signal encoding that  allows  increasing  the  bandwidth  of  a  channel  in  which  data transmission and data reception are carried out by systems from several antennas, the GSM standard.
