An appropriate cost function is constructed which avoids the use of the logarithm likelihood function that is lack of robust to the noise correlation, moreover, our method have many advantages such as, low complexity, suitable for coherence signals, etc.

• 构造适当的代价函数，避免了对数似然函数的使用，该方法对色噪声协方差矩阵特征值分散具有稳健性，同时具有较低的计算复杂度和适用于相关甚至相干源等优点。
