The procedure for synthesis of four-position radio signal to adapt data communication intelligence system to structural interference effect is proposed. This procedure is based on multi-criteria optimization methods of code sequence ensemble. The vector of criteria for the radio signal synthesis includes elements for increase AWGN and structural interfer-ence immunity, as well as improving cross-correlation characteristic. It is shown that the synthesized signals increase radio noise immunity to structural interference effect by more than 5 dB (compared to QPSK signal by direct-sequence spread spectrum with ensemble of supplemented maximum length sequence) with improving cross-correlation characteristic. These characteristics indirectly define sensitivity to mistakes of clock system. At the same time the quality of the synthesized radio component entanglement information symbol at errors clock system is improved by more than a factor of 2, and the side-lobe level of ACF criterion 5% less.
