This paper deals with the distribution of the instantaneous power (IP) in single carrier (SC) modulation. An upper bound for the complementary distribution of the IP is found using the Chernoff bound. It is also shown, as a "by-product", that the amplitude of an SC signal does not have a Gaussian distribution. The results obtained may be used to evaluate the peak factor, especially for small roll-off factors. [ABSTRACT FROM PUBLISHER]

Proposes a method based on amplitude limiting and forward error correcting (AL-FEC) coding for the reduction of the peak-to-average-power ratio (PAPR) in orthogonal multicarrier modulation (OMCM). Disadvantage of OMCM; Statement of the problem; Comparison to existing peak reduction method.

The algorithm of the optimal power loading strategy for a frequency-selective band limited channel with assigned value of the Shannon capacity, which minimises power of the transmitting multicarrier signal, is proposed. The comparison of this strategy with the uniform power loading shows that the offered strategy provides the power gain, which strongly depends on the dynamic range of the channel transfer function and can exceed 4 dB.
