This paper analyzes the relationship of symbol synchronization error and carrier phase in OFDM system. According to this, a joint estimation algorithm is proposed. A matrix is reconstructed, and a linear fitting is completed by QR matrix decomposition. The symbol timing and carrier phase is got by this joint estimation. The simulation results show that in a(More)
To date, in the struggle against diseases and the development of TCM, what we lack is wisdom rather than knowledge. Studies on pharmacology of traditional Chinese medicine are facing critical challenges on how to select the proper parameters or targets to represent the pharmacological evaluation system. With seven steps of optimized modules established by(More)
An accurate and reliable method of high-performance liquid chromatographic fingerprint combining with multi-ingredient determination was developed and validated to evaluate the influence of sulfur-fumigated Paeoniae Radix Alba on the quality and chemical constituents of Si Wu Tang. Multivariate data analysis including hierarchical cluster analysis and(More)
