Description
technical field [0001] The invention relates to the field of ultra-wideband pulse waveform design, in particular to an ultra-wideband pulse waveform manufacturing method based on an adaptive pulse forming factor. Background technique [0002] Ultra-wideband technology emerged in the late 1950s and developed rapidly after the U.S. Federal Communications Commission announced its civilian use. Since the power spectrum utilization rate of ultra-wideband pulse waveforms is very low and basically submerged in noise, its signals can be compared with Bluetooth, Various wireless communication systems such as the Global Positioning System share spectrum resources without interfering with each other, providing a solution to the nearly exhausted wireless spectrum resources. There are many ways to realize ultra-wideband pulse waveform design, such as using wavelet to design ultra-wideband pulse, but the carrier needs to be shifted, and the implementation process is complicated, while usi...
