Outline of Final Research Achievements |
In this research the throughput performance of a non-orthogonal multiple access heterogeneous network with joint detection is evaluated through computer simulation as well as experiments. In the assumed system, a macro user terminal and a pico user terminal are assumed to be capable of applying joint detection to both desired and interference signals. Numerical results obtained through computer simulation have shown that the joint detection improves system throughput by about 0.2 bit/subcarrier/user at a cumulative probability of 0.5. The numerical results obtained through experiments have also shown the same tendency as those obtained through computer simulation. Also the joint detection achieves the best bit error rate as compared to the other schemes.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果はヘテロジニアスネットワーク型セルラシステムだけでなく,隣接基地局間の干渉の影響がシステムスループットを制限する第5世代移動通信(5G)システムにおいても適用されうる.特に分散アンテナ型5Gシステムにおいては分散基地局が連携してユーザ端末を収容する.送信側の干渉制御だけでなく,本研究の受信側干渉除去を取り入れることにより,システムスループットを改善することが見込まれる.
