说明:  采用MATLAB编程,产生一个16QAM基带信号,并进行实数倍插值计算。要求符号率为1 MSymbol/s,采用均方根升余弦滤波成形,滚降系数=0.5。产生{…1,0,1,1,…}的伪随机序列,经过映射、4倍成形滤波、FIR半带滤波、实数倍内插滤波,最后输出4.315倍时域/频域响应。给出信号序列经过各级滤波的时域、频域结果
(Using MATLAB programming, resulting in a 16QAM baseband signal, and the real multiples of the interpolation calculation. The requirements of symbol rate 1 MSymbol/s, the root mean square raised cosine filter shape, roll-off factor = 0.5. Generate {1,0,1,1, ...} of the pseudo-random sequence, mapping, four times the shaping filter, FIR half-band filter, in fact, several times interpolation filter, the final output of 4.315 times the time domain/frequency domain response. Given the signal sequence through all levels of filtering the time domain, frequency domain results)
