摘要翻译：
使用已知的方法使用视线(LOS)测量来定位移动台(MS)。如果采用非LOS(NLOS)测量，这些方法可能会产生较大的误差。本文提出的基于IMAT方法的NLOS稀疏恢复算法(SRNI)将NLOS视为未知变量，并在此基础上对欠定系统进行求解，强调系统的稀疏性。通过仿真研究了SRNI算法与其它传统算法的性能。结果表明，SRNI算法在处理大的盲源组合时速度足够快，在较少的盲源数目时也是准确的

英文摘要：
  Well-known methods are employed to localize mobile station (MS) using line of sight (LOS) measurements. These methods may result in large error if they are fed with non LOS (NLOS) measurements. Our proposed algorithm, referred to as Sparse Recovery of NLOS using IMAT (SRNI), considers NLOS as unknown variables and solves the resultant underdetermined system emphasizing on its sparsity feature based on IMAT methods. Simulations are conducted to investigate the performance of SRNI in comparison of other conventional algorithms. Results demonstrate that SRNI is fast enough to deal with large combination of BSs and also accurate in lower number of BSs
