摘要/Abstract：
在对双向数字式无线内窥镜系统通信信道特征分析的基础上,给出了一种适应于超短距离高码率双向数字式无线内窥镜系统的自动请求重传(ARQ)机制及其动态自适应包长的确定方法.试验与仿真结果表明,该ARQ通信机制不仅保证了图像传输的高质量,而且还能保证传输一帧图像的效率和在规定时间内正确传输一帧图像的效率均能达到最优.
By analyzing the characteristics of the communication channel in the bi-directional digital wireless endoscopy system, this paper presents all efficient ARQ scheme with dynamically adaptive packet length for the system with high data rate and ultra-short communication distance．Furthermore, this paper also presents a novel method which is capable of dynamically adapting packet length so that it can approach the optimum value for varying channel bit error rates．The simulation results and the way to realize the ARQ scheme aye given out in this paper．
