It is non-invasive, painless and effective. Extensiveness and variety of the specific sensations (Deqi phenomenon) during EHF-puncture re-flect intensive reactions of the patient’s organism and provide individualization of therapy. EHF-puncture is a step of integration of traditional Chinese with modern Western medicines.展开更多

In this paper, an improved partial transmit sequence (PTS) scheme based on combining the grouped discrete cosine transform (DCT) with PTS technique is proposed. In the proposed scheme, the adjacent partitioned data are firstly transformed by a DCT into new modified data. After that the proposed scheme utilizes the conventional PTS technique to further reduce the PAPR of the OFDM signal. The performance of the PAPR is evaluated using a computer simulation. The simulation results indicate that the proposed scheme may improve the PAPR performance compared with the conventional PTS scheme, the grouped DCT scheme, and original OFDM respectively.展开更多
