Aimed at the cyclic character of GPS C/A signal,a blind adaptive beamforming algorithm for Global Positioning System(GPS) is proposed in this paper,which combines the Cyclic Adaptive Beamforming(CAB) algorithm with subspace technique.
This paper gives an algorithm for computing invariant rings of reductive groups in arbitrary characteristic.
The algorithm presented here computes a geometric characteristic of this action in the case where G is connected and reductive, and $\rho$ is a morphism of algebraic groups: The algorithm takes as input the
We present an algorithm for computing the invariant field k(X)G.
More precisely, we give an algorithm for computing a nonempty open subset of X with a geometric quotient.
We show that the rate of convergence for this reconstruction algorithm is geometric and computable in advance.
