Description

л ции трех поднесущих настот в каждом передатчике. , Таким образом, в .эфире образуетс  единый параллельный-.составной сигнал, СОСТО5ПЦИЙ - из шести поднесущих частот, причем этот сигнал принимаетс  одним приемником. Применение изобретени  экономит полосу частот, занимаемую тропосферной системой св зи в эфире, и упрощает при емное оборудование, так как вместо нескольких приемников, охваче П1ых параллельной автоматической регулировкой усилител  (АРУ), используетс  один при емник с обычной А1У.The three subcarriers are present in each transmitter. Thus, a single parallel-composite signal is formed in the ether, COMPOSITION of six frequency subcarriers, and this signal is received by one receiver. The application of the invention saves the bandwidth occupied by the tropospheric communication system on the air and simplifies receiving equipment, because instead of several receivers, including parallel automatic amplifier amplification (AGC), one receiver with a conventional A1U is used.
