Bridging the Gap Between Parallel and Serial Concatenated Codes

摘要

Previously, it has been shown that parallel concatenated convolutional codes (PCCCs) can be modeled as a special case of serial concatenated convolutional codes (SCCCs). In this paper, we focus on this relationship with a goal of providing a parent code design that generates PCCC, SCCC and a family of hybrid code performances that bridge the gap between the two. The proposed code is very flexible since a single encoder can produce the entire range of outputs while possessing the same decoder structure to retrieve the input data. Simulation results of the error rate performance of these codes vs. signal to noise ratio are plotted. Finally, an insight into design and analysis of good parent codes is provided.
