Abstract: This paper is mainly about the theoretical method to analyzing the frame error rate of Rate Compatable Punctured Turbo (RCPT) codes and the throughput efficiency of the RCPT-ARQ system. The time-varying trellis method is proposed to calculate the input-output weight enumerating function of RCPT codes. Based on the Sasons tight bound, the upper bound of frame error rate of RCPT codes is achieved. Then the performance bound of the RCPT-ARQ system can be calculated. The theoretical results show great consistence with the simulation results. -
