GPP based open cellular network towards 5G

Due to 5G's stringent and uncertainty traffic requirements, open ecosystem would be one inevitable way to develop 5G. On the other hand, GPP based mobile communication becomes appealing recently attributed to its striking advantage in flexibility and re-configurability. In this paper, both the advantages and challenges of GPP platform are detailed analyzed. Furthermore, both GPP based software and hardware architectures for open 5G are presented and the performances of real-time signal processing and power consumption are also evaluated. The evaluation results indicate that turbo and power consumption may be another challengeable problem should be further solved to meet the requirements of realistic deployments.
