FIELD: radio engineering, communication.SUBSTANCE: information 1 consisting of five pulses is encoded in form of a series of one positive pulse, two positive pulses, each magnified N times, one negative pulse magnified N times and one positive pulse, and an information 0 consisting of five pulses is encoded in form of a series of one negative pulse, two negative pulses, each magnified N times, one positive pulse magnified N times and one negative pulse, wherein N is a positive number greater than 1; the obtained sequences are transmitted to a data transmitting medium, and the received signal is compared with a reference signal by cross-correlation at the receiving side.EFFECT: obtaining a clear signal with high level of interference and longer range of signal transmission.2 cl, 5 dwg |
