In order to realize the phase-inversion symmetric spread spectrum communication technology, this paper proposed a new spread spectrum communication method by combining the phase-inversion symmetric method and the spread spectrum communication according to the noise relativity in time domain and the anti-noise principle of phase-inversion symmetric method. Through the simulation and experimental verification,...
An adaptive Extended Kalman Filter is derived for integrating inertial measurements from gyros, accelerometers with GPS pseudorange and pseudorange rate measurements. The adaptive filter uses an estimator based on state residual to provide a positive definite estimate of the process noise covariance matrix. The Genetic Algorithm is utilized to optimally determine the estimator’s parameter which is...
