Description
−コントローラは、ワイヤレス電気通信システムのワイヤレス送信器から、パイロットシンボルの数NPを受信することが可能である。
−以下の開示および関連する分析は、他の通信方式(signaling scheme)にも拡張可能であるが、ここでは、バイナリ位相シフトキーイング(BPSK:Binary Phase Shift Keying)変調だけが考慮されている。
−雑音および干渉は、加算ホワイトガウス雑音(AWGN:Additive White Gaussian Noise)と共にモデル化されるが、これは、以下の開示から明らかとなるように、以下の推定方法の適用を制限するべきものではない。
−送信は、固定された持続時間のタイムスロットに構成されており、各タイムスロットは、既知のパイロットシンボルおよびデータシンボルを含む。
−チャンネル減衰および位相シフトは、タイムスロット全体で固定されていると仮定し、確率変数としてというよりも、既知の定数として扱われる(フェージング仮定(fading assumption)はない)。
