1. An apparatus, comprising:
- a modem situated between water and an underwater device, the modem configured to;
demodulate a signal received from the water into a first signal and a second signalwhich are linearly and nonlinearly processed to create a bit stream for transmission to the device; and
modulate a bit stream received from the device into a transmitted signal in order to impose the transmitted signal through the water.

Abstract
An apparatus and method are provided for communicating over power lines. The apparatus includes a coupling modem that is situated between a power line and a device. The coupling modem is configured to demodulate a signal received from the power line into a sine signal and a cosine signal. The coupling modem is also configured to modulate a communicated bit stream received from the device into a transmitted signal in order to impose the transmitted signal onto the power line.
