Embodiment Construction
[0037] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0038] When the transmitting device and the receiving device communicate with each other, they are often affected by the space environment. The receiving end needs to estimate the space to improve the accuracy of communication information transmission. In order to realize the estimation of the space, it is necessary to design the transmitted waveform, and the structure of the waveform frame is as follows: figure 2 As shown, contains the training sequence and data. The training sequence is used for spatial estimation and the data is used to transmit the required communication information. The assembly of the data frame at the transmitter is as follows image 3 As shown, it includes steps such as inverse fast Fourier transform, adding cyclic prefix, and adding training sequence. The analysis of the data frame at the receiving end is as follow...
