Dear all,
I have to write a program which will take a user query from a website. I mean there will be a text box in the website which will take the input from user. Then that query will be sent to google. Now I have to record headlines of all the responses of the google(first page only) and...
the various options I can think are
1) DC chopper
2) Dual COnverter
3) take the help of AC and use rectifier
4) PWM inverter
Just search basic text books of machines, drives and you will find n number of options,
I am just learning about CDMA so I want to implement just basic processes in MATLAB to get a better feel.
Like I might have to implement receivers, transmitters, channels, various ways to code etc etc. There is no plan to implement very high level thing.
I want to learn CDMA technologyg along with Matalab Simulations. Please tell me about some book or give me some links where I can get started. I have fairly good working knowledge of Matlab but with CDMA I am null.
Regards
Vishal

Best for students like us who are doing project and do not need to have a deep understanding of subject.This will give you overall idea and the one which suits you,go for a deep study of that.
The book is posted somewhere on this forum.
planar antennas design
Hi
I have a problem of designing a microstrip planar antenna which can operate in range<1GHz.
I need as large bandwidth as possible.So please tell me how to operate large bandwidths around 500-600MHz at such low frequencies(that means antenna operates in...
Hey
You can make a programmer of your own.I am attaching some files.This is pretty cheap and it really works.Attached file has circuit diagram and some theory and some relevant datasheets .

How do you define your good bandwidth?
For microstrip 20 to 30 MHz is a great bandwidth.So you can look for the attached paper.It resonates at 911 and BW of 23 MHz.

I am sorry
The paper is attached at the link
The post by me and the name is "half of soln.pdf"
In LM series of op-amps there are a number of ICs which can provide a current upto 5A.May be you can look at those.I used them to drive my motor which required 3.5A.
Re: WIPL-D
Hi Jian,
This certainly gives better result but now also it is not accurate enough.I am attaching the paper which shows this design.It says that antenna resonates at 911MHz.
But,you pointed out the blunder which I was doing.Thanks a lot for that otherwise I would have fabricated the...

Hi jian,
Is my approach of developing metal layer is correct?
I am using ''grow metal layer ..." option which comes in layer window when right clicked over any polygon.Type of metal is defined in basic parameter dialog box.
Also one constraint with my IE3D version is that it...
wipl-d reference
Hi
I want to tell one thing.I have used wipl-d and ie3d both.I simulated some of the designs in papers and one thing I noticed is that IE3D does not give accurate results when it comes to finite thickness patches.When it comes to infinite thin patches the story is other war...
