Reduction of peak power to average power ratio in a multi-carrier signal

摘要

This invention includes, the symbol which consists of the subcarrier of the deck (33) and, the decoding processing at least in one receiver support and/or regards the multiple carrier transmission method of the signal which the pilot subcarrier for one which is improved processing (36) with the data subcarrier (35) with is included at least. Position and the reference level in the time frequency space of the pilot subcarrier it is known in the receiver. This method includes the step which modifies the phase the pilot subcarrier reference level of one subset, the pilot subcarrier inside particular subset regarding at least respectively in order to make peak electrical anti- mean power ratio smallest, symbol of a certain given (33) concerning, and/or making use of the data in order to revise amplitude. The data in order to revise takes three another values at least, transition between values of two pilot subcarriers which the inside of subset on the frequency axis continues is fixed.
