Telecommunication Entropy

Telecommunication Entropy can be regarded as the fundamental unit of information that is being transferred, received and/or stored with the passage of time. The information being transferred or received as electromagnetic waves having both wave and particle and stored in electronic circuits as charges by virtual of transistor capacitor or gate capacitance such as RAM and ROM devices. There is also flow of the stored charges on the huge number of transistors and gates and it is being conceived by us as data flow between the electronic circuits. Such signal manipulation is done and studied under ....

Huffman encoder decoder VLSI design Systematic Block Diagram

Huffman systematic VHDL block diagram Note: Click the picture below to understand clearly The picture below shows the huffman encoder decoder vlsi design systematic block diagram using the verilog HDL or VHDL codes and implemented on Xilinx ISE software. About the picture: This is a block diagram showing Huffman Encoder/ Decoder VLSI implemented block diagram. Huffman encoders decoders are source encoder decoder that are widely used in image and video compression. The circuit above has gates within it (shown below) that actually performs Huffman algorithm calculation and is based on concept of compactization of bits to lower ....

Dowload Xilinx EDA software for free

Here I want to share download link for Xilinx ISE 13.4 for free. Xilinx is one of the most popular EDA software that is used by professional engineers and companies to produce VLSI FPGA architecture design, optimization and prototyping. The Xilinx software is one of the most expensive EDA software and it's competitor FPGA vendor is Altera. With Xilinx you can do all kinds of electronics design using logic gates and optimize the logic gates for power, speed and area. As an example you can create simple counter, multiplexer, encoder, adder, subtractor and use those building blocks to model real application ....

VLSI Architecture and Design for MPEG Encoder Decoder

VLSI design gate level diagram This article is about the design of source encoder and decoder using Huffman algorithm that are widely used today, eg MPEG Encoder. First systematic block diagram of essential components such as Discrete Fourier Transform(DCT), Run Length encoder, Huffman Encoder are  explained. Note that decoder are same and only encoder are different manufactured by different companies. Next the verilog and vhdl codes are obtained for the block diagram components and then xilinx eda software is used to simulate and synthesis the HDL codes to obtain encoder schematic layout, gate level design schematic showing ....

ITU-T recommendation for telephone numbering plan for PSTN

As of now, ITU-T recommends E.164 standard for the telephone numbering plan for the PSTN. Rec E.164 defines use of prefix "+" for international call followed by 15 digits. The 15 digits includes country code(cc), the national destination code(NDC) and the subscriber number. The national destination code(NDC) refers to the combination of the area code and the exchange code. Exchange code is the code number of the PSTN switch. The following different codes makes up telephone number. Country cod  National Destination Code (NDC) Subscriber Number 1. Country Code: Country code are ....

CBRT System implementation within IN(Intelligent Network)

CRBT Signal flow in IN network CRBT(Color Ring Back Tone) is a Telecommunication VAS in which the caller can hear songs tune if the called party has CRBT enabled. This article explains how CRBT operates within the Intelligent Network architecture. The MSC (or SSP) must support the CAMEL Application Part(CAP) Phase 4 (or INAP CS2). The MSCs, SCPs and IPs are all interconnected as shown in the figure. The IPs(Intelligent Peripherals) are responsible for playing the CRBT tunes as directed by the SCP. The IN has separate SCPs dedicated for CRBT. The number of SCP depends on the number of mobile subscriber the Network Operator ....

SMSC SMPP Server

Two SMPP server in Cluster configuration SMPP(Short Message Peer to Peer) is a standardized protocol that handles the communication between SMSC and other SMS entities. It is an interface between the SMSC and NON-PLMN SMEs ( Short Message Entity). Typically it specifies the interface used between the SMSC and ESME ( External Short Message Entity) systems. This SMPP protocol may be implemented over a variety of underlying communications protocols X.25 or TCP/IP over internet or leased line by pluging in the IP cables into the SMPP server and opening the correct SMPP port. ....

SMS Messages between ESME Server and SMSC Server

This article explains the processes involved during sms messaging from a ESME server to the SMSC server. This helps in understanding the underlying sms messaging concept which can be applied to design of ESME. First the meaning of elementary components are explained. ESME(External Short Message Entity) is the name given to SMS Server(s) or SMS provider external to the SMS service provider network. Usually ESME server are owned by private business companies or government organizations that use SMS messaging service to provide various sms application such as Mobile Commerce(advertising), Mobile ....
