【摘要】 连续相位调制由于其具有恒定包络幅度且对任意的调制信息序列能保持信号的相位连续,从而能够有效的改进信号的频谱特性。因此,在现代通信系统中得到了广泛的应用。本文将介绍一种全响应CPM信号的最大似然块检测接收法,并且还对该方法的性能采用调制指数为2/3的CPFSK信号进行了评估。该方法的最大优点就是简化了接收端的处理。更多还原

【Abstract】 The continuous phase modulation has the constant amplitude and its phase is continuous, which make the signal has a very good power spectrum. The technology is widely used in the modern communication system. The paper examines maximum - likelihood block detection of uncoded full response continuous phase modulation (CPM) signal over an additive white Gaussian noise (AWGN) channel. The CPFSK signal corresponding h = 2/3 is treated as the example of the method. This noncoherent receiver is very useful because of the simplicity of the implementation.更多还原
