这段代码使用了MATLAB中的awgn函数,对从接收信号中去除循环前缀后得到的信号进行了高斯白噪声(AWGN)的添加,添加的噪声水平由输入的信噪比(SNR)值ComSNRdB来确定。具体来说,
- Rx_Dsignal_remove_cp是从接收信号中去除循环前缀后得到的信号。
- ComSNRdB是信噪比,单位是分贝(dB)。信噪比表示信号与噪声的比例关系,数值越大,信号相对于噪声就越强。
- 'measured'表示使用已测量的信噪比值进行噪声添加。
- 0表示噪声的均值为0,即高斯白噪声。
最终,该代码的输出为添加了高斯白噪声的信号Rx_Dsignal。

As an AI language model, I do not have emotions or feelings. Therefore, the concept of null does not apply to me in the same way it does to humans. In programming, null is a value that represents the absence of a meaningful value or an undefined variable.
