Outline of Annual Research Achievements

平成26年度は,初年度及び2年度において設計・開発された種々の通信方式に対するシミュレーション評価とその高精度化,および専用FPGAによるトータルシステムの実現を行った。項目毎の研究計画は以下の通り。
(1)コグニティブ方式のための環境センサー設計(鳥取大)。(1-1)Winner II モデルに基づくチャネルモジュールを再設計し,無線通信環境推定アルゴリズムの高度化を実現。(1-2)アジマススプレッド,Kファクタ推定による,BER, PER改善に関する提案アルゴリズムを再構築した。
(2)多様な通信環境下での高速通信システムの方式設計(北大)。(2-1)(1)の成果にあわせて,マルチチャンネル無線通信環境モデルの高速化を行い,(2-2)高性能MIMOデコーダーシステムのフィールド実験による評価・検証,(2-3)キャリア周波数とサンプリング周波数のジッタ問題を解決する実用性の高い新方式を開発実現した。
(3)最適低消費電力化技術の開発(北大)。(3-1)(1)および(2)にあわせた動的アーキテクチャによるRTL設計,(3-2)コグニティブMIMO-OFDMシステムのトータルシステムの設計と評価・検証を行った。
(4)システムの最適制御とデータリンク層とのインターフェイス実現(九工大)。(4-1)「劣悪環境下高速通信」及び「最適低消費電力通信」を同時に実現する新制御機能の性能評価,(4-2)QoS型MAC/LLCの実装と性能検証を行った。さらに,カメラの映像を,実時間で無線伝送するデモシステムの開発を行った。(4-3)同時に,大容量データ通信を実現する低消費電力型の超高速型MAC/LLCの設計・開発を行った。
(5)さらに,上記を統合したコグニティブMIMO-OFDMシステムのFPGAによる実現とそのフィールド実験,およびトータルシステムのLSI設計を行った(北大,北見工大)。
