Specifying the transmission rate as the indicator of system throughput, the paper proposes an improved parallel algorithm of color sensitive graph coloring principle based on allocation adjustment factor for centralized cognitive radio communication network. By using the allocation adjustment factor, the spectrum allocation can better balance the total transmission rate of the system and the allocation...
The sea level rise has great effects on the security of coastal projects. The definition of check water level has always played an important role in coastal constructions. Under the circumstance of sea level arising, as time passes, the security of high check water level will descend eventually. This paper demonstrates that the sea level of inshore area of China has a tendency of ascending in general...
Based on Tian huangping GIS Substation, very fast transient over-voltage caused by disconnecting switch operation of GIS is simulated and calculated in this paper with ATP-EMTP program. The effect of protection measures on equipments is compared and analyzed, such as adding opening and closing resistor, MOA, R-C absorber, and Ferrite Rings. Also the measures are analyzed with considering the actual...
A novel frequency offset estimator is proposed and implemented in a 1 Gbit/s real-time coherent receiver to demonstrate all-digital frequency offset compensation up to plusmn0.4 symbol rate.
