To cancel phase noise which causes the bit error rate of OFDM systems degradation, a novel orthogonal-polarization-based phase noise self- cancellation (OP-PNSC) scheme in the polarization dependent loss (PDL) channel is proposed. In the proposed scheme, the orthogonal polarizations are utilized to transmitted orthogonally polarized signals which are added together at the receiver to cancel phase...
This paper proposes a new access authentication protocol for electric vehicle in a secure and efficient way. The proposed protocol employs identity based aggregate signatures to achieve access authentication. It has the characteristics of local signals, identity based, etc. For security, the new protocol can support mutual authentication, message integrity and replay attack resistance. For efficiency,...
To suppress late-time oscillation in time marching algorithms of solution of time domain electric(TDEFIE) and magnetic field integral equation (TD-MFIE), it needs to accurately evaluate the time-domain impedance matrix elements and choose the appropriate temporal basis function. The paper accurately computes time-domain impedance matrix elements by transforming space-time integral of the source cell...
