Description

いくつかの実施形態では、外部通信システムは、複数の送信アンテナを使用して受信機でヌル結合信号を作成し、信号対干渉比を増加させることによって、送信アンテナに起因する受信アンテナでの結合電力の量を減らすように構成されている。これは、非常に弱い後方散乱信号でも、受信機で回復できることを意味する。 In some embodiments, the external communication system uses multiple transmitting antennas to create a null-coupled signal at the receiver and increases the signal-to-interference ratio to couple at the receiving antenna due to the transmitting antenna. It is configured to reduce the amount of power . This means that even very weak backscattered signals can be recovered by the receiver.
