dense band
1.Channel-extensire multi-protocol Transfer is a technique for WAN,which is suitable for dense channels,multiple protocols,and low-band with applications. The paper provids the design and implementation of the technique by cPOS and FPGA.
3.The core of the active galaxy is known as Active Galactic Nuclei (ab.AGN), which has bright and dense nuclei, with polarized non-heat continuous radiation in radio, optical and X-ray band. There exists strong atomic and ionic emission, with the ability to send out more energetic photons than normal galaxies.
