Tone reservation technique combined with active constellation extension for PAPR reduction of OFDM signal
To overcome the drawbacks of existing tone reservation(TR) techniques,an efficient TR algorithm combined with active constellation extension (ACE-TR) was proposed for reducing the peak-to-average power ratio (PAPR) of or-thogonal frequency division multiplexing (OFDM) signal.By means of a specially...

| description | To overcome the drawbacks of existing tone reservation(TR) techniques,an efficient TR algorithm combined with active constellation extension (ACE-TR) was proposed for reducing the peak-to-average power ratio (PAPR) of or-thogonal frequency division multiplexing (OFDM) signal.By means of a specially designed iterative procedure and a joint optimization approach for PAPR and bit-error-rate (BER) performances,ACE-TR was able to obtain both an im-proved BER and minimized out-of-band interference while reducing the PAPR effectively.A comprehensive theoretical analysis was presented,and some important results including the bounds of achievable PAPR gain,BER bound,and maximum iteration number were derived.Specifically,by adaptively adjusting the iterative parameters in the optimization approach,more trade-off flexibility between PAPR reduction and BER performance can be offered to satisfy various de-sign requirements.Simulations demonstrate that ACE-TR can dramatically decrease the number of required it ions to reach the desired PAPR with low computation complexity.In addition,the transmitted OFDM symbols using the pro-posed ACE-TR have less in-band distortion and lower out-of-band spectral regrowth than traditional TR algorithms. |
