AbstractDue to the high redundancy of ultra-wideband (UWB) radio frequency (RF) signal receiving channel and the channel's non-rotation invariance, the signal-to-noise ratio (SNR) of signal transmission is increased. In order to solve this problem, a circularly symmetric algorithm for the UWB RF signal receiving channel based on spectrum compression cannot effectively reduce the redundancy of UWB RF signal receiving channel; the channel does not have rotation invariance; and the effect of noisedoi:10.1515/phys-2020-0121 fatcat:qmtrclsqvvaedh2k4uf6qmxkze
