Research Abstract

本年度、私たちは低速アナログ-デジタル変換回路(ADC)サンプリングに基づき、高解像度の圧縮チャネル推定法により、スパースマルチパスブロードバンド協調ネットワークと双方向中継ネットワーク(TWRN)の研究を行った。まず、低速ADCのサンプル抽出し、協調ネットワークにより変調される広帯域通信システムにおける高解像の圧縮チャネルの推定方法を提案した。また、スパースマルチパスブロードバンドMIMO-OFDM-TWRNにおける高解像の圧縮チャネル推定法の検討を行った。
これまでの研究成果は、下記の4つにまとめることができる。
1、一対一ブロードバンド無線通信を対象として提案した圧縮検出理論に基づくチャネル推定法は、既知トレーニング系列を短縮できるので、線形チャネル推定法より高い伝送効率を達成できる。
2、協調ネットワークと双方向中継ネットワークを含む協調通信へ圧縮検出理論に基づくチャネル推定法を拡張した。
3、圧縮検出理論に基づくチャネル推定のための検出行列の設計法を提案した。これにより、チャネル推定精度を更に向上できるようになった。
4、低速アナログ-デジタル変換回路(ADC)サンプリングを用いる高解像度圧縮チャネル推定法を提案した。
