- In this dissertation , i do analysis and research on the cell communication net - based position technology and channel model . and i give out a position algorithm of anti - nlos , and simulate it . and i also introduce the constructure of the positioning system and the evaluation
本文在分析研究有关蜂窝移动通信网络的定位技术和相关信道模型的基础上，提出了一种抗nlos (非视距传输， non - lightofsight )的定位算法。 - Ruilan s bws3500 broadband wireless access system is capable of solving effectively the fundamental problem of selective frequency attenuation caused by multi - path interference . therefore , it is capable of providing generalized access ( non line - of - sight or quasi line - of - sight transmission )
瑞澜公司的bws3500宽带无线接入系统可有效地解决多径干扰引起的“选频衰落”这一根本性问题，因此能够实现普遍化的接入（非视距或准视距传输） 。 - At first , by using the feature that the excess delays of nlos propagation follow the exponential distribution , the los propagation parameters are reconstructed and the toa parameters measured from all bs are preprocessed . then , the ms ' s position is estimated by the los locating algorithm with the preprocessed data . finally , to mitigate the effect of the errors in reconstructed parameters , the estimated results are smoothed
首先，利用非视距传播时延服从指数分布的特点，对不同基站一次测量的数据进行预处理，重构视距传输参量；然后，对处理后的数据采用视距定位算法估计移动台位置；最后，对估计结果进行平滑后处理，以减小重构出的参量误差的影响，进一步提高定位精度。
