Taylor Series Expansion Method and Its Performance Analysis

The channel model suitable for TDOA techniques is discussed, and the typical location TDOA algorithm, Taylor series expansion method, is analyzed. The traditional Taylor series expansion method is improved by solving its convergence problem. Then, the performances of the improved method are simulated under different channel environments and cellar base station distributions. And, a comparison is made between the improved Taylor series expansion method and the other methods in influences of various parameters on the performances.
