The project you are indicating is a legacy one. Luckily there is a lot of material. Your challenge is gonna be how to stay away and be unique in this pursuit.

If may I suggest - try to take a look at Mat-lab image processing library. There are millions of ideas you can gather by looking at sample projects.

Easy shmeezy stuff - obvious to the bone and with far reaching implication is that you can make a project in image compression and retrieval. If you find it too hard there are gonna be algorithms on net. Data compression works on white space and change delta formations.

Other things include image recognition but that goes hard, as we proceed to different apps for this particular software. Oh yes, DSP is totally S.W stuff. Another idea - My major project in bachelor was DSP as well. I made echo cancellation of voice channels in the day when there was no voip. Something you can do as well, with VoIP so big now, it has great implications. Mind you, it is echo cancellation, not echo suppression as in regular PSTN. echo suppression kills 2 way full duplex communication. I used FC65 series DSP processor.
What E&C grads mostly miss out largely is electronics hardware experience. Try to do such a project where u get mostly hardware skills and decent programming and modelling skills.

eg: WSN.....wireless sensor networks, they need sensor's, interfacing, signal conditioning, programming, etc.

Such projects demonstarte ur ability of understanding and working around a system.

just simulating in matlab would limit ur scope. Remember that a very good understanding of hardware and it's potential n limitations is required to make an efficient and robust system.
PC interface Program
# C program for the motor


     #include 

     #include

     void main(void){

     outportb(0×378,0xFF);

     }

    That’s it ,you just set all your data pins to 1.

    8 Output pins [D0 to D7]:

    they are pins to be interfaced with motor . in ur parallel port they
    are pins starting from 2nd to 10th pin and ground is from 18th pin to
    23pin

    outportb(,);

    here FF : value to be present on data pins

     #include

     #include

     #include

     main()

     {

     outportb(0×378,0×00); ———STOP MOTOR

     sleep(2);

     outportb(0×378,0×01);———MOVE MOTOR(CCW)

     sleep(2);

     outportb(0×378,0×02);———MOVE MOTOR(CW)

     sleep(2);

     outportb(0×378,0×03);———MOVE MOTOR(Break!)

     sleep(2);

     return 0;

     }

 



The Sleep(n) function tells the port to hold [Latch] the command for (n) seconds.


want an idea about the project ?
I came across the same concept implemented using simple digital IC's, In which they have placed person counter at entrance and exit(no matter whether ppl enter from exit and exit from entrance..the sensor was smart enough to count entered and exited ppl,
when the total become zero the circuitry sends signal to power relay which turn off FAN, Tubelights and all othe things which are not suppose to be in ON state.

This project was published in EFY previously using 74xx IC's and 555 , huge PCB since no MCU was used.

Now you can do the same using MCU, or Even a Proximity Sensor plus CAMERA interfaced with PC and any Freeware image processing tool can become a smart system. Since monitoring ppl at public place can be done easily using CCD CAMERA with any Image processing tool (MATLAB..may be.)
project in embedded system...?
i've got an idea which will help you guys understand embedded systems and communication as well.

You need to make satellite tracking system, where in you need to know he type of mount of your antenna, on the basis of which you will write the program to save the coordinate of the satellite on daily basis. You park the antenna at the rise time of the satellite (or wherever it can be received). Then the antenna automatically tracks the satellite till it sets. and then again gets parked at the rise time of the next day!!!


How's that? I don't know how many of you find it a boring proj. but its quite interesting for me... try it... if yo come up with reasonably good working thing... you have done it!!!!
Project in communication?
Im interested in doin some basic project to learn practical application of communication engineering related to radio broadcasting (in beginning may be limited to my hostel only)...


Cool... That is absolutely fine. As far as a basic project is concerned, what you can actually do is something to understand the basic concepts of communication. For that what I think that you must do is, to make a low frequency oscillator (prob. 10MHz), then make an amplifier for the same freq. (you can use J310 FET). This is your backend part of your project. The very important part is the antenna. The purpose of your project will decide the type of antenna. If you want to (let us say) survey radio interference around your hostel, you have to make wide band antenna(e. Log-periodic actually something ahead of basic. but still, if u are interested enough). Otherwise as you said broadcasting, just make 10 MHz oscillator and amplifier. Making a transmitter is another issue that you should think after the receiver which should also be not much hard. Working at low frequencies can include approximations but not for high frequencies. 10 MHz is low enough.
Suggestion for  IC
1.Well If you need to transmit data only then you can o that using transistors only, no need of IC's as such. Even using super regenerative receiver you can receive data too!

2. Better I may suggest is to go for FSK based transceiver thank ASK, since you are interested in data transmission.

3. for ASK you can still use TDA IC I mentioned above just add a schmitt trigger at out put to get digital data out of TTL level.

4. If you have idea about HT12 Encoder Decoder use that to serialize your data with added address and command words, you can then give data parallely to HT12 Encoder and then give its output to any RF module like 433Mhz available in hobby shops.

5. If you wish to design the whole circuit by your own, go for super regenerative reciever used in toy cars, they are simplest and proven transistorized data receiver.

6. Try Maxim MAX1473 or similar other FSK IC.

7.jap . hu / electronic / rf . html may be useful to you, they have 433 Mhz module diagram using BJT n OPamp only.
A very Important Suggestion!!!!
Hello Everybody guys !! I am very happy that such information exchange is going on here. But I have a complain. Though I am not the moderator... I want to tell my reaction to this activity....

I think if one thinks about any project by himself... like what innovative thing can be made instead of searching for projects from someone... I also suggested some proj. to one guy here... but if one wants to make a career in communication... he needs to innovate a proj. from his understanding and doubts about the field. It usually happens that a suggested project is just copied... or the internet anyway gives everything right from the schematic... the need is to understand the concept...

Please do not misunderstand.... this is my reaction.... but needs definitely not to be overlooked...
This is the way we can create good engineers in India..
Cheers !!!
