摘要：
At least one parameter of a signal is determined, wherein the signal is a sinusoidal signal including noise, wherein the parameter includes at least one of a frequency of the signal, and an angle of a phase of the signal. The frequency of the signal is determined iteratively based on a linear relationship among the frequency of the signal, samples of the noise, and samples of the signal using a statistical correlation among the samples of the noise. During a current iteration the statistical correlation is updated based on the frequency of the signal determined during a previous iteration, and the samples of the signal are updated with values of the signal during a current period of time.

确定信号的至少一个参数，其中所述信号是包括噪声的正弦信号，其中所述参数包括所述信号的频率和所述信号的相位的角度中的至少一个。 基于信号频率，噪声样本和信号采样之间的线性关系，使用噪声样本之间的统计相关性迭代地确定信号的频率。 在当前迭代期间，基于在先前迭代中确定的信号的频率来更新统计相关性，并且在当前时间段内信号的值被更新。
