Patent ID: 7321629

Claim:
A method for encoding and transmitting the side information related to peak-to-average power ratio (PAPR) reduction in a multicarrier system, comprising the steps of: (a) performing multicarrier modulation for data to be transmitted and generating a data modulated signal, then executing a procedure related to said PAPR reduction; (b) encoding said side information for generating coded side information; (c) allocating a plurality of sub-carriers for transmitting said coded side information; (d) performing multicarrier modulation for said coded side information and generating a side information modulated signal; and (e) attaching said side information modulated signal to said data modulated signal for generating a transmitted signal; wherein said PAPR reduction procedure is based on either a PAPR level of said data modulated signal or that of said transmitted signal to determine PAPR reduction parameters which are said side information.
