Joint reduction of peak-to-average power ratio and out-of-band power based on subcarrier weighting in OFDM systems
Considering the conflict of PAPR and OBP reductions in OFDM systems,a new method based on subcarrier weighting was proposed for the joint reduction.The symbols on subcarriers were multiplied by optimal weighting vector to reduce PAPR and OBP jointly,and an improved GA was used to calculate the optim...
