STUDY OF RANDOM SCAN TV TRANSMISSION.
Abstract
The report is concerned with the study of the modulation-demodulation and synchronization problems arising in random-scan TV signals, which are characterized by the pseudo-random selection of the spacial positions of the TV elements. The transmission channels considered were troposcatter and line-of-sight propagation in the S- and X-Band. Both analog and digital modems were studied. Also, the modulation and synchronization problems of a simulated random scan based on a repetitive linear sweep followed by a point selector are discussed. (Author)
