SHAPER OF DISCRETE ORTHOGONAL FUNCTIONS Russian patent published in 2015 - IPC G06F1/25 

FIELD: radio engineering, communication.

SUBSTANCE: shaping device of discrete orthogonal multilevel signals includes two switching devices and a signal delay unit. The fifth output of the Walsh function shaping unit is connected to control inputs of the first and the second switching devices, the fifth and the fifteenth outputs of the Walsh function shaping unit are connected to upper and lower information inputs of the first switching device respectively, the fifth and the thirteenth outputs of the Walsh function shaping unit are connected to upper and lower information inputs of the second switching device respectively; output of the second switching device is connected to input of the signal delay unit; the second output of the Walsh function shaping unit is connected to control input of the third switching device; outputs of the first switching device and the signal delay unit are connected to information inputs of the third switching device; output of the third switching device is connected to the first inputs of all multipliers; output of Walsh i-function of the Walsh function shaping unit is connected to the second inputs of all the multipliers; outputs of the multipliers are outputs of the shaper of discrete orthogonal functions.

EFFECT: increasing interference immunity of shaped discrete orthogonal signals.
