Research Abstract

本研究では,ネットワークシステムにおける各種デバイスの電源容量や回路規模等のリソース制約を考慮した,データ圧縮,誤り制御符号化及び暗号化方式の研究を行う.具体的には,以下の3項目について研究を行う.
(1) 小型携帯端末等のリソース制約が厳しい機器において動画像を効率的に圧縮するため,Distributed Video Coding (DVC)の高圧縮率化/高画質化に関する研究を行う.
(2) 小型携帯端末等において,情報源符号化(圧縮)と通信路符号化(誤り制御符号化)を組み合わせて低計算量で効率的に行うため,Joint Source-Channel Coding (JSCC)に関する研究を行う.
(3) 高速なネットワークで接続された分散ストレージシステムにおいて,誤り制御符号化/復号化を分散処理とすることにより,各ノードにおける計算負荷を分散し,同時に高信頼化を実現するためのDistributed Error Control Coding (DECC)に関する研究を行う.
