“…OFDM is a frequency division multiplexing (FDM), but is completely different from the past the FDM [2] .The OFDM receiver is actually a group of demodulator achieved by the FFT.It can move the Different carrier to zero frequency,and then integrating within one symbol period.Other carrier signal does not impact on the extraction of information,due to mutually orthogonal with the Integrated signal.OFDM data transmission rate is also related to the number of subcarriers.Sub-carriers of the OFDM system can select the modulation method adaptively according to the channel, and can achieve the switching between a variety of modulation [3] .…”

With the development of wireless technology, wireless network bandwidth is increasingly high require.OFDM modulation technique can be used to more fully utilize the available bandwidth.The paper studied the important role of the cyclic prefix in OFDM.We get the simulation figure when delay spread exceeds the cyclic prefix.Simulation results show that when cyclic prefix accounted 20%,the power loss is less than l dB,and information rate loss of up to 20%.But inserting a cyclic prefix can eliminate the influence of the inter-carrier caused by the inter-symbol interference and the inter-carrier caused by multipath interference.

“…Meanwhile, the aircrafts establish communication links with GSs via the moving air interface without handover during the whole flight. Additionally, the MIMO transmission can involve the the broadband A/G transmission schemes, such as L-DACS1 and NCI-OFDM [7,8]. Besides the communications service, these schemes can even provide the positioning and navigation based on the GSs [9,10].…”

Hinted by the terrestrial massive Multiple Input Multiple Output (MIMO) communications, a massive MIMO system for Air-to-Ground (A/G) communications is proposed, i.e., due to the aviation environment, multiple Ground Stations (GS) are organized to support the moving air interface for civil aircrafts with the full-band access. The aircraft can access the system with the massive MIMO antenna arrays facilitated in multiple GSs without handover. Compared with the traditional A/G MIMO scheme, not only the system capacity is enlarged, but also the variance of the capacity is greatly mitigated.
