| Summary: | As a strong supplementary technique to the traditional mobile communication networks,the concept of device to device was introduced into the future 5G mobile communication networks.To solve the problems of base station-free transmission manner and the complex interference environment induced by the non-coordinated user data transmission,an adaptive transmission power allocation algorithm based on game theory and fuzzy logic was proposed,to utilize the system power and frequency in a more efficient way while minimizing the interference to other users.Through the simulation results,the proposed algorithm outperformed the conventional equal power allocation and distributed water-filling algorithms in the aspect of user received data rates.
