In the scenario of multiple access communication, the spectral sidelobes and peak-to-average power radio (PAPR) problems of orthogonal frequency division multiplexing (OFDM) must not be ignored. This paper proposes a novel precoding scheme that ahead of inverse discrete Fourier transformation (IDFT) is presented to jointly suppress the in-band-out-of-subband (IBOSB) radiation and high PAPR in orthogonal...
In this article, based on grey relational analysis method, relational polarity analysis for the anti-respiratory syncytial virus effect of compositions from Baikal skullcap root was studied. The compositions with reinforcement effect on the therapeutic index of anti-respiratory syncytial virus were found and ranked.
With the ubiquitous application of Internet and wireless networks, H.264 video communication becomes more and more popular. However, due to the high-efficiently predictive coding and the variable length entropy coding, it is more sensitive to transmission errors. Error concealment (EC) is just an approach to utilize the spatial and temporal correlations to conceal the corrupted region. In this paper,...
