Abstract :
An optimized ambiguity search method is described in this paper focusing on speed and reliability. The method has incorporated several existing fast ambiguity search concepts and the ambiguity search speed can be further improved. In addition to the improvement of the ambiguity search speed, special attention has been paid to the improvement of the reliability of the ambiguity search process. Several theoretical and practical aspects involved in an ambiguity search algorithm are also addressed which have not been explored in previous literatures
