Self-decoupling coupled-fed patch antennas are designed in this letter. The self-decoupling mechanism is based on the weak-field region formed by T-shaped probe feed and radiating of antenna element itself. When another identical placed region, high isolation between two elements can be achieved without adding extra decoupling structures. To validate mechanism, a dual-element array initially bu...

Multiple-input–multiple-output (MIMO) system offers a promising way for high data rate communication over bandwidth-limited underwater acoustic channels. However, MIMO not only suffers from intersymbol interference, but also introduces the additional co-channel which brings challenge channel estimation and equalization. In this article, we propose novel interference cancellation (IC) methods ha...
