Here You Get how 3G work, Go inside WCDMA Technology and wcdma rf optimization.

Correlation in WCDMA

How Correlation works in WCDMA ? Correlation measures similarity between any two arbitrary signals. Identical and Orthogonal signals: Correlation is used to measure similarity of any two arbitrary signals. It

WCDMA Interleaving

How WCDMA Interleaving ? Effect Interleaving is used to reduce the probability of consecutive bits error Longer interleaving periods have better data protection with more delay Channel coding works well

WCDMA Channel Coding

Effect Enhance the correlation among symbols so as to recover the signal when interference occurs Provides better error correction at receiver, but brings increment of the delay Channel Types No

Which Bands Used in WCDMA ?

There are different band in different country but most of commonly used band we will discuss here. Main bands : means basic band when 3G commercial launch by Private or public

3G Spectrum Allocation

How 3G Spectrum Allocation? 3G Spectrum Allocation is different in different country but mainly its all having as per below figure. ITU has allocated 3G Spectrum Allocation 230 MHz frequency

What are SRNC and DRNC in WCDMA

SRNC and DRNC are concepts for a connected UE. The SRNC handles the connection to one UE, and may borrow radio resources of a certain cell from the DRNC. Drift

lub Interface in 3G WCDMA

The 3G Iub interface is the terrestrial interface between NodeB and RNC. The Radio Network Layer defines procedures related to the operation of the WCDMA NodeB. The Transport Network Layer

WCDMA Iu PS Interface

Here I write about Iu PS Interface in WCDMA. WCDMA Protocol Structure for Iu PS The Iu PS protocol structure is represented in below image. Again, a common ATM transport

WCDMA Iu CS Interface

WCDMA Protocol Structure for Iu CS The WCDMA Iu CS overall protocol structure is depicted in below image. The three planes in the Iu interface share a common ATM (Asynchronous
