The details of OFDM, the transmission scheme used in LTE, are described in this chapter. Basic aspects related to OFDM transmission, such as cyclic prefix insertion, FFT-based implementations, single-frequency-network operation, and selection of OFDM parameters are discussed.

In this chapter, a more detailed overview of OFDM or Orthogonal Frequency-Division Multiplexing will be given. OFDM is the transmission scheme used for 3GPP LTE and is also used for several other radio-access technologies, for example WiMAX  and the DVB broadcast technologies .
Transmission by means of OFDM can be seen as a kind ...
