Modify the Gray-coded modulation example (COMMDOC_GRAY) so that it uses a pair of square root raised cosine filters to perform pulse shaping and matched filtering at the transmitter and receiver, respectively.-Modify the Gray-coded modulation e

平方根升余弦脉冲实例。两个SQRC滤波器的级联组合就成为一个零ISI的滤波器。此程序用于获得平方根升余弦脉冲。-Square root raised cosine pulse instance. Cascade combination of the two SQRC filters to filter a zero ISI. This procedure used to obtain the square root raised cosine pulse.
