图形中的图标是“Tx”(蓝色曲线),“Decimating FIR Filter”模块的输出信号被看作是QPSK接收信号,图形中的图标是Rx(红色曲线),通过对比发现,经过了“Decimating FIR Filter”模块的作用,接收信号的带外功率明显减少了,即在有效带宽之外,红色曲线的带外功率明显要低于了蓝色曲线的带外功率...

interpolating FIR filter means we can only use integer values for this. Also, remember that using an RRC filter /will/ result in ISI. You have to use a secondary RRC filter to remove the ISI. In another posting of yours, I also saw that you used both an RRC decimating filter and the...
