B_Q_Q16_AWGN.rar是BPSK,QPSK,16QAM在高斯信道下的系统性能仿真，给出了信噪比SNR与误比特率BER 的关系。 16QAM是16进制的正交振幅调制在高斯信道和瑞利信道下的信噪比SNR与误比特率BER 的关系。都是matlab编写的-B_Q_Q16_AWGN.rar BPSK, QPSK, 16QAM in AWGN channel system performance simulation, given the relationship between the S

调频广播中，为了提高音频高频率端的信噪比，在发射端进行的预加重处理。-FM radio, in order to improve the high frequency end of the audio signal to noise ratio, performed at the transmitter pre-emphasis.
