Nowadays, blind detection is represented by the constant modulus algorithm(CMA), High-order moment , Signal subspace.

目前盲方法以常模算法（CMA）、高阶矩、信号子空间、自适应方法为代表。

Furthermore, we show that the constant modulus cost function with non-canonical constraint is strictly convex under some conditions.

然后证明具有非标准约束的常数模准则在适当条件下是严格凸的。
