The CDMA reverse link uses a different coding scheme to transmit data. Unlike the forward link, the reverse link cannot support a pilot channel for synchronous demodulation (since each mobile station would need its own pilot channel). The lack of a pilot channel is partially responsible for the reverse link’s lower capacity than the forward … Read more
All about Antennas. What is, How Works, How Many Types. Here I write about antenna which include what is antenna, How it works, Antenna classification, Specifications of antenna, Working Band and what is antenna gain other than this about antenna I will write next. What is Antenna Antenna is a device which converts an electric … Read more
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
