Forward error correction

[Ron Marcus]

I have a project that has a simplex wireless link. I need to encode the data in such a way that there is some form of error correction, not just detection. There is no way to poll the transmitter again if an error is detected. Any ideas that can be used with PIC processors?

Thanks,
Ron

So, you break your Data into small packets with a Packet-Header and Check-Digit on each, and repeat each packet two, three or four times. At the receive end, any packet with a Check-Digit failure is simply ignored...

or...

You send each byte say five times, at the receive end you must have at least three out of the five identical to accept that byte...

or...

Oh...And thanks for the other options too!
