说明: 对于已定义的包含从0到15的整数的列向量xsym,就可以利用modem.qammod对象的modulate方法来调制它。其中M值为16,亦即为码字表的大小。
对已调制信号可采用awgn函数添加加性高斯噪声。其中比特能量与噪声功率谱密度的比值,Eb/N0,设置为10dB。
(The method comprising modulate integer from column vectors xsym 0 through 15, can use the defined object modem.qammod modulating it. Wherein M is 16, i.e., a codeword size of the table. Modulated signal can be used for awgn function to add the additive Gaussian noise. Wherein the ratio of bit energy to noise power spectral density, Eb/N0, is set to 10dB.)
