Construction method of membership functions in different packet loss environment in heterogeneous network

The invention provides a construction method of membership functions in different packet loss environment in heterogeneous network. The method comprises: analyzing EM algorithm of Gaussian mixture model, and initializing the EM algorithm with a potential function-based method; under the condition of the coexist of network congestion and wireless error code, applying the improved EM algorithm to the estimation of membership functions in different packet loss environment according to training sample ROD statistical result; performing simulation verification, reaching good distinguishing effect for the definition of membership functions in different packet loss environment. The method provided by the invention has good practical application value.
