Aiming at the limitation of Lo S propagation by VHF/UHF single-channel radios,the feasibility of VHF/UHF singlechannel BLo S propagation by troposcatter is derived firstly.Based on the analysis above,a scheme of non-symmetric diversity troposcatter communication is presented,which can realize BLo S communication by adding BLo S transmission waveform and founding adding-energy communication station without changing hardware of single-channel radios. In the end,the feasibility and validity of the scheme are p...
