Complex correntropy function: Properties, and application to a channel equalization problem
作者：
Highlights：
• We define a new generalized similarity measure between complex random variables.
• A complete deduction is presented and important properties are studied.
• Complex correntropy has overcome classical methods in a channel equalization problem.
• Now it is possible to use correntropy in problems involving complex-valued data.
