  • Video signal distribution system microwave radio link for transmitting double sideband phase modulated carrier signal
    Patent number: 5619248
    Abstract: In a video signal distribution system in which a plurality of video signals are modulated onto individual carrier signals spaced over a band of frequencies to form a composite signal for transmission over cables of the system, a point-to-point radio link forming part of the distribution system is provided in which the composite signal is transmitted as double side band phase modulation of a single microwave carrier signal.
    Type: Grant
