Channel sounding over sea surface environment

Big tankers and cargo ships anchored off the Southern coast of Singapore act as a blockage for a line-of-sight (LOS) propagation for wireless link between the shore and sea. This results in Non-line-of-sight (NLOS) propagation, affecting sea-to-land wireless transmission. For military and commercial...
