This paper adresses a method to mitigate the Peak to MEan Power Ratio (PMEPR) of Orthogonal Frequency Division Multiplexing (OFDM) signals. The idea is to use adjacent bands of the OFDM spectrum to allocate optimized subcarriers so as to decrease the signal PMEPR with the help of SOCP optimization process. This way of doing has only sense if additional subcarriers all fall under the standard spectrum mask. According to this, the proposed method does not degrade the Bit Error Rate (BER), has no bandwidth loss, does not imply any modification of the receiver and is standard compliant.
