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...

Description

technical field [0001] The present invention relates to the technical field of signal processing, in particular to a broadband data transmission waveform generation and processing method, device and system. Background technique [0002] Broadband data transmission is to meet the growing demand for data transmission. During broadband transmission, due to the wide bandwidth of the signal, it is easily affected by the space environment, resulting in a decrease in communication quality and communication efficiency. It is necessary to estimate the space to improve the transmission quality of the signal by means of coding. Contents of the invention [0003] The technical problem to be solved by the present invention lies in the problem that the broadband signal is greatly affected by the space during transmission, which leads to the problem that the communication quality is degraded. Therefore, the present invention provides a broadband data transmission waveform generation an...
