In CDMA, the mobile unit scans for available Pilot signals, which are all on different time offsets.  This process is made easier … Read more

What is Polarization Mode for antenna

The polarization is a radiation feature for indicating the vector special direction of field strength of electromagnetic wave. If unspecified, the spatial direction of electric field vector usually serves as the polarization direction of electromagnetic wave. The spatial direction of electric field vector is the direction of maximum radiation by antenna. The electromagnetic wave of … Read more
