Abstract

The invention discloses an anti-multipath anti-interference signal transmission method based on time division multiple access, and relates to the technical field of radio transmission and communication. In this method, the frequency hopping field is firstly generated according to the frequency hopping frequency sequence information, and the source data is added behind it, followed by channel coding, interleaving, modulation, segmentation, pilot insertion, scrambling, and OFDM symbol mapping, and then the synchronization field is inserted to obtain Synchronization segment burst signal; then channel coding, interleaving, modulation, segmentation, pilot insertion, scrambling, OFDM symbol mapping, and frequency hopping guard interval are performed on the subsequent source data to obtain the data segment burst signal; A demodulation guard interval is inserted between the segment burst signal and the data segment burst signal to obtain a time slot signal; finally, the time slot signal is converted into a frequency hopping signal by the radio frequency channel module and sent out through the antenna. The method has reliable and stable performance and can meet the needs of the wireless communication field.

Description

technical field [0001] The invention relates to the technical field of radio transmission and communication, in particular to a method for sending anti-multipath and anti-jamming signals based on time division multiple access. Background technique [0002] The number of users supported by the traditional continuous wave transmission system is small, and due to the continuous transmission of radio waves, the concealment ability is weak. The burst transmission technology can effectively improve the anti-intercept and anti-interference ability of the communication system by shortening the residence time of the signal in space. On this basis, the system assigns different time slots to each node, and each node in the network transmits signals in its own working time slot. This system has the characteristics of high channel utilization and low equipment cost. [0003] In addition, the OFDM communication system has the advantage of anti-multipath interference, and the frequency-h...
