Abstract

For the problem of high peak-to-average power ratio(PAPR) of transform domain communication system(TDCS) and the slow convergence of the PAPR of the traditional iterative clipping and filtering method, this paper proposed an improved iterative clipping and filtering method for TDCS signal PAPR reduction. By filtering the clipping noise introduced, this method reduced the PAPR regrowth and effectively eliminated out-of-band spectrum spread, and got better PAPR suppression effect in iteration. The simulation results show that on the one hand, this method can obtain better PAPR suppression effect, the first iteration can obtain about 1 dB performance gain compared with the traditional method and the third iteration has better performance than the fourth iteration of traditional method. On the other hand, it can improve the out-of-band spectrum performance, after filtering, the out-of-band spectrum power reduces by about 5 dB. The comparison of BER shows that the performance of system lost by the improved method is very low.
