An apparatus and method for removing noise from a frequency signal are provided. In one example, a receiver includes a front-end circuit to convert a radio frequency (RF) input signal to at least one frequency signal; a non-linear circuit coupled to the front-end circuit, the non-linear circuit generating at least one shaped frequency signal from the at least one frequency signal according to at least one non-linear transfer function; and a modulated signal detector coupled to the non-linear circuit for outputting a likelihood signal based on the at least one shaped frequency signal. 提供了用于从频率信号中去除噪声的装置和方法。在一个示例中，一种接收器包括：前端电路，用于将射频(RF)输入信号转换成至少一个频率信号；耦合到所述前端电路的非线性电路，所述非线性电路根据至少一个非线性传递函数从所述至少一个频率信号生成至少一个整形频率信号；以及耦合到非线性电路的调制信号检测器，用于基于所述至少一个整形频率信号输出似然信号。
