ABSTRACT:
A method and apparatus for diminishing a peak power to average power ratio (PAPR) in an OFDM/OFDMA communication system are disclosed, by which complexity in an OFDM/OFDMA communication system can be reduced. In an OFDM or OFDMA communication system, the present invention includes a circular shift module circularly shifting to output at least one or more data sequences according to circular shift information to be applied to each of the at least one or more data sequences converted to a time domain from a frequency domain, a combining module combining the at least one or more data sequences outputted from the circular shift module, and a PAPR calculating module calculating the PAPR of an entire data sequence combined by the combining module.
