用于干扰抑制的、使用加权LSB/USB总和的相干AM解调器
摘要：
一种处理AM无线电信号的方法，包括以下步骤：接收包括上边带部分和下边带部分的AM无线电信号，解调上边带部分和下边带部分以便产生解调的上边带信号和解调的下边带信号，响应于噪声功率加权解调的上边带信号和解调的下边带信号以便产生被加权的解调上边带信号和被加权的解调下边带信号，以及组合该被加权的解调上边带信号和被加权的解调下边带信号以便产生输出信号。还包括根据本方法的用来处理AM无线电信号的解调器，以及结合了解调器的接收器。
摘要（英）：

A method of processing an AM radio signal comprises the step of receiving an AM radio signal including an upper sideband portion and a lower sideband portion, demodulating the upper sideband portion and the lower sideband portion to produce a demodulated upper sideband signal and a demodulated lower sideband signal, weighting the demodulated upper sideband signal and the demodulated lower sidebandsignal in response to noise power to produce a weighted demodulated upper sideband signal and a weighted demodulated lower sideband signal, and combining the weighted demodulated upper sideband signal and the weighted demodulated lower sideband signal to produce an output signal. Demodulators which process AM radio signals in accordance with the method, and receivers incorporating the demodulators, are also included.
