Description
個の独立的なアンテナを備える送信端構造で構成されることができる。
は、k番目のサブキャリアにおけるNRF×Ns基底帯域プリコーダ(baseband precoder)を意味する。また、skは、k番目のサブキャリアにおける送信信号ベクトル(Ns×1)を意味し、zkは、k番目のサブキャリアにおける雑音信号ベクトル(Nr×1)を意味する。
は、波形の長さ(wave−length)、dは、アンテナ間距離を意味する。以下、説明の便宜のために、ハイブリッドビームフォーマを構成するRFチェーンの数は4であり、各RFチェーン別アナログアンテナの数は4である場合が仮定される。このとき、ハイブリッドビームフォーマは、図5のように構成されることができる。
が成立する。このとき、アナログ端子のPS(Phase Shifter)とPA(Power Amplifier)とは、等価である(equivalent)ビームフォーミング重み(beamforming weight)で表現されることができ、これは、下記の数式7のとおりである。
