FrequenceDetect

代码说明：

  分别使用LS和TLS算法，计算出混合信号的频率。该频率估计算法的数学模型是基于ARMA模型。其中还包括详细的设计报告，有一定的参考价值。(LS and TLS algorithms were used to calculate the mixed-signal frequency. The mathematical model of the frequency estimation algorithm is based on ARMA models. It also includes detailed design report, a certain reference value.)
