マイクロ波ベクトルネットワークアナライザはUWBチャネルサウンダとして多く用いられているが,スナップショット数が1回に限られること,複数到来波の相関が高くなることや送信信号が実際の無線システムと異なるといった問題がある.これに対して,帯域幅500 MHzのOFDM信号を参照信号とするUWB時空間チャネルサウンダを開発しアレーアンテナと組み合わせて,電波暗室にてTOA(time of arrival)とAOA(angle of arrival)を推定し,その有効性を実証してきた.本発表では,室内環境でのVNA及びOFDM信号伝送型UWB時空間チャネルサウンダによる,TOA及びAOAの推定結果を報告する. |

Microwave vector network analyzer (VNA) has been widely used to as an ultra wideband (UWB) channel sounder. However, channel sounders using VNAs have some limitations: there is only one snapshot; and incoming waves tend to be strongly correlated due to sounding signals of sine waves. To overcome the above issues, a UWB spatio-temporal channel sounder, employing an orthogonal frequency division multiplexing (OFDM) signal and a virtual array antenna, was developed along with a proposed technique for estimating time-of-arrival (TOA) and angle-of-arrival (AOA) of UWB OFDM signals. Comparison was carried out between the VNA- and the OFDM-based channel sounders in term of experimental estimation of TOAs and AOAs in an indoor three-path environment. |
