| 摘 要： | 非相干解调由于不需要产生同频同相的本地载波，避免了因为本地载波的不精确导致的解调信号失真，降低了在实际系统中接收端实现的复杂度。文章分析了遥测信号的一种非相干解调的算法，并进行了仿真，得出高斯白噪声（AWGN）信道中的误码曲线。

| Abstract: | When the signal is non-coherent demodulated,the receiver doesn't need a corresponding carrier with the transmitter modulated carrier wave,avoids distortion of the demodulated signal owing to the local carrier's imprecision and reduces the complexity of the receiver.Therefore,a non-coherent demodulation algorithm is analyzed and simulated.Finally we get the ber curve curve in awgn channel. |
