One signal can follow different paths and time delays before reception in a shallow water environment.

Caption

Multipath propagation results in a single signal being received (Rx) through different paths (P=1, P=2, P=3, P=4) and with different delays (lower diagram). This type of interference is modeled in channel estimation to more effectively denoise offshore transmissions.
