Abstract
To acquire the identical shortwave array signal in the lab with the one under a real atmospheric condition, the shortwave channel and the array signal are realized on the digital signal processor (DSP) chip according to the signal by the shortwave channel theory and the shortwave antenna array theory in the shortwave communication. Meanwhile the signal is modulated to the shortwave frequency band with the digital upconveter (DUO chip,and the array signal is simulated in the real shortwave communication.
