METHOD AND MODEM FOR SUBSEA POWER LINE COMMUNICATION |
摘要 |
A method for communicating binary data via an electric signal of a subsea power line includes establishing a point-to-point connection between a subsea electronic unit and a topside electronic unit for transmitting binary data via the electric signal of the subsea power line; the subsea electronic unit modulating binary data onto said electric signal using orthogonal frequency division multiplexing (OFDM), using 10-200 individual carrier bands in a selected radio frequency range; communicating the OFDM-modulated binary data via the subsea power line to the topside electronic unit; and the topside electronic unit demodulating the OFDM-modulated binary data, including passing the electric signal through a low-pass filter and passing said radio frequency with the modulated binary data through a band-pass filter. |
