主要 对无线定位TDOA CHAN算法以及TAYLOR算法进行误码仿真并且仿真了一种两算法相结合的算法 并对误码进行比较-The content is mainly to simulate Chan Algorithm and Taylor Algorithm ,then compare their error performance.Based on them,A new Algorithm combining the two type of Algorithm is also propose

TDOA算法包括泰勒，最小二乘法，chan算法及改进算法等(TDOA algorithm includes Taylor, least square method, Chan algorithm and improved algorithm)
