Study on Performance of the Best Receiver of Additive Gaussian White Noise Channel

讨论了加性高斯白噪声信道的基带数字调制技术 ,对加性高斯白噪声信道的最佳接收机性能进行了较深入的研究 ,并重点探讨了信号传输的误码率与信噪比的关系 ,得出了随着信号波形的增加可以通过减小每bit所需的信噪比来达到给定的误码率的结论 ,找到了获得最佳接收机的有效途径。

The base band digit modulation technology of additive Gaussian white noise channel is discussed in this paper. The performance of the best receiver of additive Gaussian white noise channel has been studied deeply with the stress on the relation between signal noise ratio and the bit error rate in the signal transmission. It is concluded that increasing the signal waveform, the given bit error rate is achievable by decreasing the signal noise ratio required per bit. Namely, an effective approach obtaining the best receiver is found.
