Wow !

I like that. Thanks for the answer.

Try this :
binary_in=['110';'010';'101']
dec_in=bin2dec(fliplr(binary_in))
msg_in=gf(dec_in,3)
msg_coded=rsenc(msg_in,7,3,rsgenpoly(7,3,[],1))
msg_coded=rsenc(msg_in',7,3,rsgenpoly(7,3,[],1))
msg_coded_dec=msg_coded.x
msg_coded_bin=fliplr(dec2bin(msg_coded_dec'))

Hi,

I am trying to use the Reed-Solomon encoder in the Matlab Communications
toolbox ( command rsenc). For example if you are trying to a (7,3) R-S
encoder. When you use rsenc the inputs and outputs have are alphabets in
the respective Galois fields ( GF(8) in this example). Is there a way to
convert the input and output formats such that we can input a binary
string and get a binary string of the encoder. I know there exists a block
in the Simulink blockset for this purpose - but i don't want to use
simulink. i want the simulation entirely in matlab with the comm toolbox.
