A Fast Calculation Method of Integer Ambiguity Resolution
Zhu Zhi-yu, Bing Zhang, Liu Wei-ting · 2005
The floating point solution of integer ambiguity resolution and relevant variance-covariance matrix are applied to construct the search space, from which the correct integer ambiguity resolution is picked out according to the quadratic form of least residual error. The triangle Gauss integer transform is used to decrease the value in the covariance matrix Q_(′)to reduce the search space of integer ambiguity resolution. Cholesky decomposition is adopted to improve the search efficiency. The statistic property of the search method is also briefly discussed. Results from simulation indicate that the proposed method can quicken the search speed of integer ambiguity resolution.
