Abstract

リアルタイム処理で25Mbpsの無線伝送が可能となった5GHz帯高速無線モデムを試作し、実環境での動作を確認した。遅延判定帰還型信号推定器(DDFSE:Delayed Decision Feedback Sequemce Estimator)をLSI化し、バースト通信で、周波数安定度±20ppmまで動作し、2波モデルで500nsの遅延波まで等化可能である。

5GHz band 25Mbps wireless modem system with real time processing is materialized and the excellent performance under real environment is cofirmed.The modem system with Delayed Decision Feedback Sequence Estimator(DDFSE)realized on one LSI chip can operate under frequency stability ±20ppm and equalize 500ns delay wave under 2-path model for burst transmission.
