本文论述了用自动调整编码速率使始终与信道误码率ＢＥＲ相匹配的Ⅰ型混合式ＡＲＱ系统，得出系统吞吐量最大时的最佳码速的设计过程。通过计算机模拟结果证实系统的有效性与准确性。
This paper discusses the type Ⅰ hybrid ARQ system that uses the automatic adjustment of the coding rate to match the bit error rate (BER) of the channel all the time, and obtains the optimal code rate design process when the system throughput is maximum. Computer simulation results confirm the validity and accuracy of the system.
