Forward Traffic Channel of CDMA

Forward Traffic Channel of CDMA

Forward Traffic Channel is used to Transmit Data and Signaling Information. Symbol repetition makes symbol streams at different rates adapted to those at the rate of 19.2k. The original symbol stream at  the rate
Advantages of CDMA Handoff

Advantages of CDMA Handoff

It is "soft", meaning that communication is not interrupted by the handoff. This is sometimes called "make before break." This means fewer dropped calls for users and higher customer satisfaction for operators. The handoff
Handoff Candidate Classification in CDMA

Handoff Candidate Classification in CDMA

The mobile station continuously searches for Pilots to detect the presence of other CDMA signals that have the same carrier frequency and measures the strength (received Ec/Nt) of the pilots.  When the mobile station

What is Basic work of Pilot Channel in CDMA?

A pilot channel: Assist mobile station to be connected with CDMA network Handles multi-path searching Provide the phase reference for coherent demodulation and help the mobile station estimate the transmission power The mobile station
Transmit Diversity of CDMA

Transmit Diversity of CDMA

Diversity technology means that after receiving two or more input signals with mutually uncorrelated fading at the same time, the system demodulates these signals and adds them up. Thus, the system can receive more
