On the Design of PS-RCPT Codes for LTE System

The Optimized Weight Spectrum Sequence (OWSS) is utilized as a design criterion in this paper to determine the periodic puncturing pattern and the non-periodic puncturing pattern of Partially Systematic RCPT (PS-RCPT) codes for LTE systems. It is shown that the OWSS-criterion based PS-RCPT codes outperform the Pseudo-Random Puncturing (PRP) based PS-RCPT codes. Meanwhile, it is unveiled that, the puncturing ratio of information bits should be carefully determined in PSRCPT codes generation to achieve reasonable tradeoff between the waterfall region and the error floor region performance.
