15. An apparatus for encoding and transmitting the side information related to peak-to-average power ratio (PAPR) reduction
in a multicarrier system, comprising:
a multicarrier modulator for modulating data onto multiple sub-carriers and generating a data modulated signal, wherein said
multicarrier modulator comprises a PAPR reduction device to reduce a PAPR level of said data modulated signal and reserves
a plurality of sub-carriers for encoding and transmitting said side information;
a side information coding and modulation device for coding and modulating said side information onto said plurality of sub-carriers
and generating a side information modulated signal;
an adder for combining said data modulated signal and said side information modulated signal, and generating a transmitted
signal; and
a parameter control device for PAPR reduction for determining said side information according to the PAPR level of said data
modulated signal.
