Embodiment Construction
[0093] The design purpose of the present invention is to provide a scheme in which multiple users can frequency-division multiplex pilot symbols, so that the interval between each pilot subcarrier on the pilot symbol frequency domain becomes smaller to obtain a better channel Estimation of interpolation processing effects.
[0094] The main realization principle and specific implementation manners of the present invention will be described in detail below with reference to each accompanying drawing.
[0095] Please refer to Figure 5 , this figure is the main implementation principle flowchart of the first pilot multiplexing method based on single carrier frequency division multiple access technology proposed by the present invention, mainly used in a channel estimation cycle (such as a TTI or several TTIs) ), perform pilot multiplexing processing between at least two pilot symbols time-division multiplexed with the symbols of the data signal sent by the user, and its main im...
