Method and apparatus for reducing peak-to-average power ratio in single carrier-frequency division multiple access based radio communication system

摘要

A method for reducing Peak-to-Average Power Ratio (PAPR) in a Single Carrier Frequency Division Multiple Access (SC-FDMA) based radio communication system is provided. The method includes arranging symbols mapped to predetermined sub-carrier allocation types such that phases of the symbols do not overlap, and transmitting the arranged symbols.

1. A method for transmitting a signal in a single carrier frequency division multiple access (SC-FDMA) based radio communication system, the method comprising:
selecting at least two physical layer pipes (PLPs) among a plurality of PLPs, wherein each symbol included in each of the at least two PLPs is allocated to a different subcarrier within a plurality of subcarriers included in a frequency region; configuring the signal by combining the selected at least two PLPs; adjusting first phases of first symbols included in a first PLP among the at least two PLPs such that the first phases and second phases do not overlap each other, wherein the second phases of second symbols are included in a second PLP among the at least two PLPs; determining a minimum combination order having a minimum peak-to-average power ratio (PAPR) among combination orders for the phase adjusted at least two PLPs within the signal; re-configuring the signal by arranging the first symbols and the second symbols according to the minimum combination order; and transmitting the reconfigured signal.
