Forming OFDM symbols for 4G service signals with a total working frequency band of more than 3–4 GHz

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 e...

Zusammenfassung: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.
