Comparative Study of Decorrelation Algorithms for GPS Ambiguity Solution

The decorrelation algorithms of integer gaussian,united ambiguity,the iteration,inverse integer Cholesky and LLL(Lenstra,Lenstra and Lovasz algorithm) are classified and compared respectively based on the matrix decomposition.The simulation result shows that the inverse integer Cholesky decorrelation method is better than the united ambiguity decorrelation,and they are superior to LLL method.
