Efficiency of use OFDM in the troposcatter communication channel, ways of noise stability rise

Today the OFDM method (orthogonal frequency-division multiplexing) gains the increasing popularity. It is basic of possible methods for use in the future wireless cellular systems similar 4G. Also the given method became popular in use in modern digital radio – and telecasting. In this case, in the present work the expediency and efficiency of use OFDM in the troposcatter communication systems are observed, and also ways of noise stability rise of such systems. It is shown that as a result of application OFDM – method and pseudo – casual operating frequency readjustment (PROF), that has not been used earlier in the troposcatter communication stations (TCS), it is possible to achieve de- crease influence of short-term fading, to increase the quality indices of noise stability and speed of information transfer.
