RF problem with receiving signal from three transmitters (433.92 MHz)

HI,
Currently i am working with RF projects, I come across a problem, and i would like to share with u so that anyone can clear my problem?

In my project i have three transmitter and one receiver of same frequency 433.92MHz. i had a problem when i switch ON both the three transmitter , Because my receiver is not capable to receive the signal from none of the transmitter.

But my receiver is working when I switch ON a single transmitter. Any solution to solve this problem , please help me...

Hi..
As I understood you have three transmitters and single receiver and you want that receiver should work even when all transmitters are in ON state.
I would advise your to use diversity schemes like Direct Squence or follow TDMA for system to correctly.

I Hope it helps.

Hi,

As much I know of RF tx/rx circuits you can't have multiple transmitters on same freq and expect the receiver to work fine. Either use multichannel tx & multichannel rx.!1
