LIU Pei, GE Jian-hua, LIU Gang. Performance Evaluation of the Concatenated Convolutional Codes[J]. Acta Electronica Sinica, 2003, 31(7): 1089-1091.DOI:
In this paper three systems using a concatenation of two short convolutional codes in place of a single long convolutional code are proposed and evaluated.Specifically
the systems use a
R
=2/3 with
K
=3
R
=3/4 with
K=2
and
R
=1/2 with
K
=7 code.The first two systems employ a soft decision followed by a hard decision Viterbi decoder.The most attractive feature of these systems is the reduction in the complexity of the decoders
and hence the entire system
that varies from 25% to 50% of that of the baseline system.
