根升余弦基带成形滤波器的设计及其DSP实现.最后利用系数对称特性，在某软件无线电电台系统的DSP 芯片中编程，

实现均方根升余弦滤波器的成形滤波算法-First this essay introduces baseband shaped filter theory and

requirements of an SDR system on shaped filtering. And, the author

introduces various realization methods of FIR filter presently, in

addition the author expatiate on square-root raised-cosine filter and its

design in IS-95 software defined system. Finally, the author illustrates

the shaped filter realization based on software programming using

symmetry properties of FIR filter coefficients
