    • A method of determining as to whether a received signal includes an information signal is provided. The method provided includes determining a covariance matrix from a received signal and transforming the covariance matrix into a transformed covariance matrix, wherein the transformation is configured such that the transformed covariance matrix is a non-diagonal matrix in case the received signal includes the information signal, wherein the non-diagonal matrix includes non-zero non-diagonal matrix elements. The method provided further includes determining a first function using at least one of the non-zero non-diagonal matrix elements of the transformed covariance matrix, determining a second function using at least one matrix element of the transformed covariance matrix, wherein the second function is different from the first function, and determining as to whether a received signal includes an information signal based on a comparison of a value of the first function and a value of the second function.
    • 提供一种确定接收信号是否包括信息信号的方法。 所提供的方法包括从接收信号确定协方差矩阵并将协方差矩阵变换成变换协方差矩阵,其中变换被配置成使得在接收到的信号包括信息信号的情况下变换的协方差矩阵是非对角矩阵, 其中所述非对角矩阵包括非零非对角矩阵元素。 所提供的方法还包括使用变换的协方差矩阵的非零非对角矩阵元素中的至少一个确定第一函数,使用变换的协方差矩阵的至少一个矩阵元素确定第二函数,其中第二函数为 与第一功能不同,并且基于第一功能的值和第二功能的值的比较,确定接收信号是否包括信息信号。
