Link Equation of Viral Video Service in Frequency Domain Based on Cross Entropy

Aiming at broadband CDMA mobile communication system, around video service, introduction of the concept of cross entropy, a method of link equation of viral video service in frequency domain based on cross entropy is established. From frequency domain model, the impact of corresponding parameter on the performance of viral communication network are simulated and analyzed. The simulation result shows that the probability of mobile users carrying on video service in microcell with viral mobile communication can reach to 43.34 percent. The analysis result responses the better-optimized level of the occurrence probability in frequency domain, which is mobile users carrying on video service in microcell with viral mobile communication, and soft handover probability. It supplies a method when applying the link equation of viral video service to 3G and 4G CDMA mobile communication system and its performance optimization.
