Blind PTS Receiver for PAPR Reduction in MC-CDMA Systems

In this paper, a blind PTS scheme in MC-CDMA systems is proposed. Based on the relationship between the dispreading codes and side information, the new scheme utilizes the phase recovering with the partial dispread signal, and makes the optimal decision based on minimum power error of the dispread signals. Simulation shows that compared with the conventional PTS scheme, the proposed scheme can recover the phase information without SI at the receiver and provide better frequency efficiency and transmitting performance.
