File Information

This project allows you to learn communication systems in greater depth. It contains the Simulink files (*.mdl) which are block design files of various communication systems such as AM, DSB-SC, FM, PLL, Data Acquisition, Digital Data Transmission, PCM and Delta Modulation.
The idea here is to implement experiments of a traditional communication lab using Simulink.

Most of the block diagrams are self explanatory. More information on the systems and their implementation can be found in the word documents included in the lab directories.

thanks.it was useful.

The file is too old to use. For example there is no Buffered FFT Frame Scope in DSF Blockset, and the dsp blockset is changed to DSP System Toolbox.

Badly designed labs. I'm trying Lab5 and its absolute crap!

My friend says Lab7 is badly designed.

There are a few minor mistakes in the word files in Lab 1 (says SC, but K=1). Otherwise excellent.

hola rafael:
mi nombre es javier... soy de argentina y estudio ingenieria en telecomunicaciones....esta carera es nueva...(hace cinco años que se abrio la carrera)
y.... como en toda carrera nueva hay problemas... es muy dificil aprender a simular... cuando no tenemos el apoyo teorico de un programa tan potente y de aplicacion variada como MATLAB-SIMULINK...
iré al grano rafael...
me gustaria especializarme a full con simulink.....(tengo muchas ganas de aprender)
te comento que si se programar en matlab y simular algo en simulink pero hay algunas aplicaciones que no se usarlas ....mi objetivo no es que me enseñes (si puedes) desde el principio.... te repito ya se algo, pero quisisera aprender mas.... quisiera especializarme mas...
y no se como comunicarme con las personas que mas saben del tema....
te cuento tambien que tengo muchas tareas simuladas como por ejemplo deteccion coherente de AM con PLL, o simulacion de diversas tecnicas de modulacion como por ejemplo am con portadora o BLU ....(y mas....)
lo que mas quiero saber en este momento es como puedo relacionar los bloques de simulacion continuos con los bloques que me permiten simular impedancias RLC en serie por ejemplo...(creo que estos bloques perenecen a la libreria de electronica de potencia o algo por el estilo)
bueno....RAFAEL ojala pudieras ayudarme ... porque quiero ser el mejor usando MATLAB quiero saber mas... ojala podamos comunicarnos a pesar que te escribo en español....y si tubiera que escirbirte en ingles .... bueno haria el ezfuerzo....

soy estudiante en telecomunicaciones y nesesito de su ayuda... para aprender a simular...desde ya muchas gracias... quisiera que me respondan para saber como puedo comunicarme con ustedes y saber si tengo que abonar o si es gratuito el help...
quisiera saber como puedo obtener informacion de los metodos de simulacion en simulink si tubiera alguna duda despues de realizar mis experimentos.....muchas gracias....EL QUE ESCRIBE ***JAVIER AGUIRRE***

The Idea is great, only some examples don't work and are not the same as the ones in the word documents. For instance the PLL in Lab3 doesn't work, when I create the examples which are described in the word documents they also don't work. This isn't strange since the VCO gets a frequency at its input (from the feedback loop) the VCO requires some DC at its input (DC is 0 when PLL is in lock) to lock to some signal. In the word it's mentioned that the VCO gets an error voltage and not a difference frequency but how this is done ???

It is very difficult for use

30 Jan 2002 Ronan Scaife

The basic idea of this submission is very good.
It is a great source of ideas for a virtual
comms lab.
However, we have Matlab 5.3 and Simulink 3,
and the models don't work. For instance, the
Buffered frame FFT scope is not available in
Simulink 3. The package was presumably
written for an earlier release of Simulink.
I gave up on patching the package,
and am slowly rebuilding a few of the models
and documents from scratch.
Many thanks to Dr. Khrishnaswamy for
his conceptual framework!

13 Jan 2002 Patrick Moran

This is an interesting submission but so far I cant replicate any of the "Results" in the MSWord documents. In lab 6 lab6th.doc, how do I get "DC Volts" out of the Simulink simulator. Something doesn't match. The display doesn't sample a DC value. Why is the sample rate set to .0009 HZ? Could someone explain this?

11 Jan 2002 Val Burtea

The ideea is just great.
