Orthogonal Frequency Division Multiplexing

摘要

The contribution serves as a preview of the OFDM modulation signal, which is used in cellular and other wireless networks. We look closer on this problem and we are subsequently discussed general topics. That include an issue of mobile networks in their general concept and also more insight on the network 4 and 5 generations. Within the network 4 generations, namely LTE and LTE-A is approximated architecture and properties of these networks. In a 5-generation networks that reach into realization in the future, we have discussed concepts of architecture and other features.
