Zusammenfassung:The invention discloses an LED positioning method and system combining ellipse ACO-OFDM. The LED positioning method and system are used for alleviating influence of multipath distortion in an indoor environment. An LED is used as a transmitter with unique ID for distinguishing a position thereof, a mobile receiver is based on an RSS positioning algorithm for obtaining a position self at the horizontal position, and further a trust-region technique is adopted for realizing three-dimensional positioning, so that positioning accuracy is high. 本发明公开了种结合椭圆ACO-OFDM的LED定位方法及系统，用于减轻室内环境中多径失真的影响，LED用作具有唯ID的发射机以区分其位置，并且移动接收机基于RSS定位算法以获得自身在水平位置上的定位，并进步采用信赖域技术实现三维定位，定位精度高。
