Industrial Automatic Control Systems and Controllers Annotation << Back Rising the Noise Immunity of Direct Sequence Spread Spectrum Systems with Modified Offset Qpsk A.N. Rudnev The proposed method for rising the noise immunity of direct sequence spread spectrum systems, based on cross-correlation processing of signals from quadrature channels of the demodulator. An estimate of the energy gain of the proposed method is obtained. The block diagram of the demodulator is presented. Keywords: direct sequence spread spectrum; cross-correlation signal processing; system noise immunity; energy gain. DOI: 10.25791/asu.1.2022.1337 Pp. 08-11.
