Interference Margin for CDMA

In determining RF coverage in CDMA systems, the effect of interference generated from the serving cell as well as the neighboring cells must be considered, this is in contrast to…

What is CDMA Time Diversity ?

Time diversity is a technique common to most digital transmission systems.  The Rake Receiver is used to find and demodulate multipath signals that are time delayed from the main signal….

Receive Diversity Selection and Switched Diversity

Make use of a number of receive antennas that are well separated (coherence distance) to generate independent receptions of the transmitted signal. Selection diversity: choose received signal with largest received…

How Interference Diversity of Hopping in GSM

In GSM system, the interference strength and distribution on each frequency carrier in cell are different, the carrier variation of the bursts of the same communication low the interference on…

Spurious Interference and Blocking Interference for LTE

Spurious interference Spurious interference refers to the additive interference generated by the interference source in the working frequency band of the interfered receiver. Spurious interference includes the out of band…
