Abstract:

To solve the high peaktoaverage power ratio (PAPR) problem of waveletbased orthogonal frequency division multiplexing (WOFDM), an optimizing PAPR algorithm based on linear programming is proposed. On conditional that the number of the wavelet filter banks level is fixed, the best wavelet packer basis is chosen by constructing the linear programming model and the optimal PAPR of the system can be obtained by utilizing the best wavelet packer basis to modulate signals. The analysis and simulations show the bit error rate performance of the system can be ensured, at the same time, the PAPR of the system can be mitigated by implementing the algorithm.
