OFDM (Orthogonal Frequency Division Multiplexing) signal generation method, related equipment and application system

The embodiment of the invention discloses an OFDM (Orthogonal Frequency Division Multiplexing) signal generation method, related equipment and an application system. The method comprises the following steps: acquiring parameter information of an OFDM signal to be generated; determining N first subcarriers and P second subcarriers from the M subcarriers according to a preset parameter D; and respectively distributing signal power to the N first subcarriers and the P second subcarriers in two stages, thereby determining waveforms of two stages, namely a first waveform and a second waveform, and finally generating an OFDM signal containing waveform symbols of the two stages. When the OFDM signal generated by the embodiment of the invention is used for ranging and positioning, the ranging and positioning precision and range ambiguity resistance can be improved. 本发明实施例公开了一种OFDM信号生成方法、相关设备及应用系统，该方法可包括：获取待生成OFDM信号的参数信息；根据预设参数D从所述M个子载波中确定N个第一子载波和P个第二子载波；分两个阶段将信号功率分别分配给该N个第一子载波和P个第二子载波，从而确定出两个阶段的波形，即第一波形和第二波形，最终生成一个包含
