发明名称 METHOD OF GENERATING AN AMPLITUDEN-MODULATED ISB TRANSMISSION SIGNAL AND APPARATUS FOR CARRYING OUT THE METHOD
摘要 In the case of a method for the generation of an amplitude-modulated ISB transmission signal from different AF signal (NF1,2), the signal vectors are split into signal components (x1,y1 and x2,y2, respectively), components sums (X,Y) are formed from the signal components and an amplitude signal (A(t)) and a harmonic phase signal are derived from the component sums. Amplitude signal and phase signal are then further processed separately and combined at the single transmitting tube (43) by combined amplitude modulation and phase modulation into the final transmission signal.
