OFDM-basedWirelessBroadBandSystemSimulator
基于OFDM的无线宽带系统仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found out. The output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.(OFDM-based wireless broadband system simulation It contains mainly two parts, ie link-level simulator and system-level simulator.Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx .

sparfilt
优点：1.对于信噪比高的信号滤波效果好；
％ 2.对于边沿的保护强过阈值滤波，不会产生阈值滤波情况下的过于平滑与Gibbs现象。
％缺点：1.由于对边沿信号没做任何处理，所以边沿可能会有脉冲噪声保留下来；
％ 2.计算相关系数中，如果计算出来的小波系数点位置偏差大，则相关系数计算受影响；
％ 3.需要迭代运算，迭代的噪声能量阈值选取很重要，这里以开始段无信号处估计噪声；
％ 4.需要迭代运算，所以运算量比阈值法大；
％ 5.受分解层次影响，在大尺度上小波系数点位置偏差更大，相关系数计算不准确。
％需要具体调整的地方：1.分解的尺度；()
