摘　　要：为了给适合军事通信的室外超宽带通信技术发展提供技术支持,针对跳时脉冲位置调制超宽带系统的室外信道,提出了一种基于降低噪声影响的信道估计算法。通过仿真,对该算法的性能进行了分析,仿真分析结果表明,该算法有效易行,导频个数越大,估计的值越准确。In order to surport the development of military technique of outdoor UWB, a channel estimation algorithm based on the fluence of noise - lowered criterion is applied to TH - PPM - UWB system. The performance using the algorithm is evaluated by computer simulation. The results show that the algorithm is effective and practical for TH - PPM - UWB system and the number of pilot must be large enough to guarantee adequate estimation accuracy.
