| 摘 要： | A search algorithm for the detection of a direct path signal in the presence of dense multipath in indoor environment using UWB is Woposed. This algorithm is based on signal correlation and differential coefficient. Statistical analysis of the algorithm is given out and computer simulation results are presented to validate the effectiveness of the algorithm. The results based on the algorithm pml3osed are compared with those based on Maximum Likelihood Estimator（MLE） and Peak Tracking（PT） in the simulation which shows that this algorithm achieves the highest accuracy in most cases and gives out relatively stable results in different Signal Noise Ratio（SNR）.
