hi
I am making a project in which i am transmitting the data from serial port and going to receive it at a distance of 5 meters.i need to use wireless communications.i am explaining what i did till now.correct me if i go wrong anywhere.
i almost completed the design of the receiver.only thing left out is depending on the transmitter setting up the frequency.my receiver circuit has a band pass filter and an amplifier. then i am using a fir filter in MATLAB to get a rectified output and then synthesing the data.all the above filters and amplifiers i used are digital receivers and i am using MATLAB and DSP builder to build them. if i had gone wrong in any of the above please do correct me.
my problem started with the transmitter.i wrote a "c program" to transmit the data.i just need to send a 4 bit data. taking the suggestions from this forum i made it a 8 bit data so that i can neglect the first fout bits which might be altered during the RF data transmission.
i need a simple RF transmitter that can sense the data coming out from serial port and transmit it.i am searching it on Google but didnt get anything releavent to serial RF data transmission.i dont want to buy any kit.i want to make the transmitter myself.also i am a beginner in microcontrollers.
please do correct me if i am conceptualiy wrong anywhere in any of these things above mentioned and do tell me the problems i might face in transmission so that i can rectify them before in hand.
also i would be happy if any one help me out with a schematic for RF serial port data transmission
