| Outline of Final Research Achievements |
In recent years, the mobile wireless communications are required to wide band because of emergence of rich mobile application and spread of IoT over society. The environment of wireless communications is composed of heterogenous wireless systems such as WiFi, LTE, and WiMAX, and in future it will be composed of enormous number of antennas that support communication in high frequency with 5G.
In this research, Dynamic Configuration for Multiple MIMO channel with Heterogenous Wireless Systems was devised. The method introduces sharing antennas among heterogenous wireless systems, configures dynamically Multiple MIMO channel by distributing the sharing antennas to each wireless system, and aims to maximize the sum of MIMO channel capacity of wireless systems. Additionally, Virtual Channel Bonding was devised. The bonding can aggregate the multiple MIMO channels as a single channel. The combination of them could increase application throughput in evaluation with network simulator.
