摘　　要：该文研究基于速率兼容的删余Turbo(RCPT)码的混合ARQ系统性能分析问题,提出将删余卷积码的网格图看成时变的网格图,并利用紧致界分析RVPT码的误帧率性能,进而计算RCPT-ARQ系统通过效率下界。经比较,理论分析结果与仿真结果十分吻合。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 Sason's 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.
