Hefei synchrotron radiation Light Source (HLS) is a low energy Syn-chrotron Radiation (SR) facility. The SR produced from the HLS is in a series of pulses with a strict time structure. To meet some experiments which need long interval SR pulses, a new method, local vertical bump, was proposed. Physical calculations and numerical simulations have been done to demonstrate its feasibility.

脉冲噪声会导致非负算法在迭代过程中存在过大的误差值,进而破坏算法的稳定性使其性能严重下降,对此该文提出一种基于Sigmoid框架的非负最小均方算法(SNNLMS)。该算法将传统的非负代价函数嵌入Sigmoid框架中得到新的代价函数,新的代价函数具有抑制脉冲噪声影响的特性。此外,为了增强SNNLMS算法在稀疏系统识别问题上的鲁棒性,该文还提出基于反比例函数的反比例Sigmoid非负最小均方算法(IP-SNNLMS)。仿真结果表明SNNLMS算法有效地解决了脉冲噪声造成的失调问题;IP-SNNLMS增强了算法鲁棒性,改进了算法在稀疏系统识别问题中收敛速率上的缺陷。
