N2 - The device-to-device (D2D) communication has been regarded as a promising technique to effectively upgrade the existing cellular network. Despite the intriguing perspectives of D2D technique, the performance of D2D-aided cellular network may degrade owing to the severe interference imposed by newly introduced D2D links. With a motive to deal with this problem, the key performance parameters of D2D-aided underlaying cellular networks, including the coverage probability and total data rate have been investigated. Firstly, we analyze the expressions of coverage probability for both the conventional cellular links and the D2D links, and then we give out the approximate expression of the ergodic rate for both individual links and that of the whole underlaying system. After that, in order to optimize the performance of the system in terms of throughput, more parameters closely related to the channel capacity are studied. Finally, the simulation results revealed that the best values for key parameters (e.g. the density of D2D users) are attainable, and the total data rate can been greatly improved according to our proposed strategies.
