简化的OFDM系统仿真，其中暂未考虑扰码和卷积码，物理层参数采用802.11a参数，1个长训练符号与6个OFDM数据符号构成1帧，信道为单径rayleigh衰落信道，其中最大多普勒频移为100Hz，信噪比0-30dB，调制方式为QPSK和16-QAM。(Simplified OFDM system simulation, which yet consider scrambling and convolution codes, physical layer parameters using 802.11a parameters, a long training symbols and six OFDM data symbols constitute a channel for single-path rayleigh fading channel, one of the largest Doppler shift is 100Hz, the SNR 0-30dB, the modulation scheme is QPSK and 16-QAM.)

泰勒级数展开算法是需要初始估计位置的递归算法，在每一次的递归中通过求解TDOA测量误差的局部最小二乘来改进估计的位置。 本程序基于MATLAB，对泰勒级数展开算法进行了仿真。初始位置的选取很重要，建议和其他简单的算法进行协同，对信号源位置进行定位。 希望对研究信号源定位的同志有所帮助。(Taylor series expansion algorithm is the need to estimate the location of the initial recursive algorithm, in every recursive TDOA measurement error by solving the partial least squares to improve the position estimate. The program is based on MATLAB, the Taylor series expansion algorithm for the simulation. The selection of the initial position is very important, the proposed algorithm and other simple coordination, to locate the signal source location. Want to locate the source of research help comrades.)
