CDMA means all depedancy on power control here i write on Power Control Inaccuracy in cdma. Traffic capacity of CDMA systems is increased by implementing an appropriate power control scheme…

The Reverse CDMA Channel is composed of Access Channels and Reverse Traffic Channels. These channels share the same CDMA frequency assignment. Each Traffic Channel is identified by a distinct user…

Implement security through encryption (both control plane (RRC) data and user plane data) and integrity protection (for control plane (RRC) data only), it is the responsibility PDCP layer. A PDCP…

Cell selection consists of the UE seeking stronger cell on all supported frequencies of each transport supported rat until it finds a suitable cell. The main requirement for cell selection…

Depending on the type of measurement, the UE can measure and report any of the following: serving cell; list of cells (e.g., cells shown as part of the object of…

Here I write some small notes on connection Re-Establishment procedure in LTE. In a number of cases of failure (eg failure of radio link failure of teaching RLC unrecoverable error,…

Effect of Interleaving In GSM the speech frame is transmitted over eight consecutive bursts. The fast fading causes bursty bit errors that degrade the efficiency of the convolutional coding. The…

To protect the logical channels from transmission errors introduced by the radio path, many different coding schemes are used. The diagram below illustrates the coding process for speech, control and…

To Improve Error Protection and Security of Data the Data is Interleaved and its type is Diagonal let’s check how it works. The diagram below illustrates, in a simplified form,…

As All Channel Interleaving in GSM but control channel is some different interleaved its interleaving rectangular lets understand how it. The diagram below illustrates, in a simplified form, the principle…
