BER performance of non-UEP and UEP codes, constructed by three different construction algorithms. All codes have 
and allowed 
. The random code has good UEP capability already for 
dB, while the PEG code and the PEG-ACE code have less UEP capability for 
dB. All UEP codes have better average performance than the corresponding non-UEP codes, except for the random code at low 
.
