Forming OFDM Symbols for 4G Service Signals with a Total Working Frequency Band of More than 3-4 GHz

摘要

The basis of the solution of the problem of forming OFDM symbols with a set of 4G service signals to deliver them to mobile terminals moving with the speed of 300-350 km/h along the autobahn is given. In this case, the total amount of mobile terminals can be several thousand, and the bandwidth for each signal should be on the order of 6-12 Mbit/s. Two variants of generating a modulating signal without and with using the principles of TDMA technology are offered.
