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
