单载波频域均衡SC-FOMA的主要优点是调制后的信号PAPR特别低，所以E-UTRA把它单载波传输(SC-FOMA)技术作为上行链路(UL)的主流候选传输方案之一。(single carrier )

matlab源码用于简单的地震分析和显示 有明确的程序用法，使用简单。(seismic analysis and display )

说明：  蒙特卡罗方法计算面板数据单位根检验统计值之有限样本密度分布(Monte Carlo method panel data unit root test statistics of the density distribution of the limited sample)

Designs an FIR filter given a desired frequency response H_des(w). The design is judged by the maximum absolute error (Chebychev norm). This is a convex problem (after sampling it can be formulated as an SOCP). minimize max |H(w) - H_des(w)| for w in [0,pi] ( where H is the frequency response function and variable is h (the filter impulse response). )
