Description
本出願は、2016年2月4日に出願された米国特許仮出願第62/291,238号明細書の優先権を主張し、その開示内容は、参照により本明細書に組み込まれる。
LTE、LTEアドバンス、IEEE802.11nおよびIEEE802.11acなど、現在使用されているほとんどの無線通信システムは、環境を理解して、例えば、スループット率を動的に最適化するか、またはシステムのロバスト性を改善することができるように、周知の信号またはパイロット信号経由で無線チャンネルの状態を継続して検知している。そのような検知構造は、継続して改善すると考えられ、その構造は、自己推進型の較正システムと、送信された信号と受信された信号との差を最小にする、無線信号の事前補償および事後補償技術が可能である。
