摘要： An apparatus is provided for reducing a peak-to-average power ratio (PAPR) in a wireless communication system having multiple transmit antennas. A symbol generator generates symbols to be transmitted via the multiple transmit antennas, and a PAPR calculator calculates a PAPR value for each symbol. A detector detects a maximum PAPR value among the PAPR values of the symbols. A controller outputs a control signal to reduce a PAPR value of a corresponding symbol when the detected maximum PAPR value exceeds a reference PAPR value. A PAPR reducer reduces the PAPR value of the corresponding symbol upon receipt of the control signal.

摘要： In an MCM communication system in which one frame includes at least one pilot symbol of a predetermined length and at least one data symbol of the predetermined length, to transmit the pilot symbol for time synchronization and frequency synchronization, a first pilot sequence of a length shorter than the predetermined length is generated, and a second pilot sequence of a length shorter than the predetermined length is generated. Here, the second pilot sequence is different from the first pilot sequence. The first and second pilot sequences are repeated a predetermined number of times. The pilot symbol is generated by combining the repeated first and second pilot sequences, and then transmitted.
