The authors have proposed the signal decomposition technique as the powerful solution to mitigate the large peak-to-average power ratio (PAPR) to be addressed in OFDM transmitters, and the simple noise elimination techniques working together with the signal decomposition in receivers. It is shown that the proposed signal decomposition technique improves the PAPR by 4dB and doubles the power added efficiency (PAE) at the complementary cumulative distribution function (CCDF) of 1%. In order to show the feasibility of the proposed techniques when they are applied to MIMO transmissions, BER performances of the proposed techniques are also demonstrated.
