the interference suppression of spread spectrum systems is treated as constrained minimum mean output energy (MMOE).After an orthogonal decompose procedure for transforming the MMOE problem to unconstrained minimum mean square error (MMSE) one and a construction for state equation and observation equation
and then the blind Kalman filtering (BKF)
i.e.
absence of a desire signal
is developed and analyzed.The research results indicate that the BKF algorithm is insensitive to variations in the correlation matrix
fast response to the changing environment
and close to level of optimization with iterative operation.Hence
it is superior to the blind least mean square (BLMS) and blind recursive least squares (BRLS) algorithms.
