A method codes data in a transmitted signal. The transmitted signal comprises multiple subcarriers with orthogonal frequencies. The signals are modulated corresponding to a given subset of the subcarriers of the transmitted signal in order to encode information. The signal is modulated corresponding to least one reserved subcarrier depending on at least one optimization criterion relating to a quality of the overall transmitted signal. In order to enhance the quality of the transmitted signal, the optimization criterion depends on at least one first quantity relating to a peak-to-average-power ratio of the transmitted signal and on at least one second quantity relating to an out-of-band power of the transmitted signal.

A control apparatus for a hull with a four-cycle engine installed thereon can perform engine stop processing by quickly detecting a turnover state of the hull while suppressing a turnover determination delay due to noise superposition. The apparatus includes a turnover determination part that determines, based on a detection signal from a turnover detection switch, whether the hull is in a turnover state, and an engine stop part that stops the engine upon determination of a final hull turnover state. The turnover determination part increments a detection ratio counter each time a detection signal indicative of a hull turnover state is input thereto, counts up a continuous turnover counter each time the detection ratio counter value indicates a predetermined determination ratio value or above. When the continuous turnover counter value reaches the predetermined determination value or above, the turnover determination part determines that the hull is in the final turnover state.
