Hello

I am modelling a magnetic recording channel and implementing the reed
solomon encoder and decoder for better error correcting codes. My system
input is the random binary interger. then I AM using RS (256,239), is that
any ways that i can input the binary string for RS Encoder and Display in
binary after the encoder ? The binary output of the RS encoder is that go
to the magnetic recording channel and then go throught the RS decoder at
the end.Is that any method that i can convert the binary output from the
recording channel into the GF elemets that can input to the RS Decoder and
finally display the RS Decoder output in binary again?
