Simulink mapping

Started by asq_smk April 27, 2004
hi all
iam doin a communications project on simulink
i have to code a binary stream using doubinry line
coding then add white guassian noise then decode it
and use some mapping window to check if the decoded
signal is right or wrong ie if i sent 011011001 it
will be line coded to 0110-1-100-1 (doubinry rule)
well i made everything but got stuck on the mapping ,
after decoding i must check the received 3 bits at a
time to see if they comply with the doubinry coding
thus checkin if it contains any errors,
how can i do that? please if anyone needs
clarification send me

and many thanks in advance
