i am 3rd year student of electronics and communication.Can any buddy please give me a simple Mini project with the help of hardware and simulation tools on digital communition. i have no idea on this subject(digital communication) so please give me a simple but good project...
Analog comm, digital comm are important along with Mobile comm and Microwave LOS comm. If you are interested in the design part, Signal Processing, Random Processes are subjects you should be good at as well
I have several digital signals from a microchip into a CCD chip. The signals coming out of the microchip is very noisy. What is the best way to reduce the noise/glitches? The noise is small compare to the logic level, but might add some noise to the CCD output. If the best way is to use a buffer, is there any difference between a common bus bu
Hi everyone, I am comm system guy, I have no good background in digital design, so I need your help. I have a project to design a transceiver , so I did most of the algorithms using MATLAB and need to go toward the HDL . So I need an easy way to do that, that is suitable to me . I heard that simulink is good for this task, and here are my questi
I have started studying after a long time. i am following book of SKLAR of digital comm. Can any body explain me that how can a judge a signal by seeing its function that it is ebergy signal or power signal. I am attaching three questions. Kindly explain me in detail their integration as well [i
Transmission may be for both types analog and digital. In analog transmission, the data is analog. In digital transmission, the data is digital and processing is digital as well.

Plz if any one could reply & help me about a matlab code for the digital communication BPSK QPSK 16 QAM just help me give me ideas or hints something like that
qpsk.....wat u do in this is, u use the phase as also a form to represent signal rather than just the magnitude as in the case of dpsk, etc..... for better understandin...go through some basic digital comm books....simon haykins,etc...
so please suggest me a good theisis topic
hello: can any one guide me in choosing my semester project for analog and digital comm systems. it can any thing like AM,FM etc. i will require to implement this practically therefore i will also require the cct diagrams. thanks.
FDMA is basically Analog technology and the oldst one. TDMA is digital and being used in GSM. CDMA is newest of all, whre all users are allocated a distinct code. Added after 2 minutes: For easy and basic understanding I will recommend " Data comm and Networking" by Behrouz Forouzan
Quite strange that there is video for both analog and digital design, however, there is no system level course. Why?

Hi everyone, does someone know manufacturers of optical components (transmitter, receiver, ...) for ANALOG communications. There so many components for digital comm that i can't find one for analog com. Thanx in advance Ghost
when designing a digital comm system, i'd like to use fixed-point computations through all the data paths rath than double, whick is default in Vissim. But i found it not very convenient to constraint the blocks to some specified fixed-point precision. Are there any easy ways to do that? Thanks anyway.
does anyone know any links to download pdf for various topics on digital communications? Not a PDF, but a good book: Principles of communication systems by Taub Shilling A lot of theory to just about every topic. Properties of various comm channels, coding modulation, error correction, etc.
