摘　　要：从加解扰系统中重要的技术指标"寻址速度"入手,分析了影响该指标的软硬件和协议因素,提出了综合的自适应高速寻址算法和相关协议设计,并简要分析了算法设计的理论基础。通过统计分析可知本算法寻址速度平均提高了近48倍,并且设计的协议在多项技术指标上取得了重要进展。An active addressing algorithm and data transport protocol of the Addressable Sc rambling / Descrambling System is proposed in this paper. Starting on the addres singspeed of the ASDS, it analyzed the factors of hardware,software and protoc ols which affect the performance parameters. The analysis of the theory basis of algorithms is also conducted. It is a very encouraging finding that the propose d speedup technique has performed very well. Comparing to the current methods in most of ASDS, the addressingspeed of ASDS of the algorithm is speeded up ne arly 48 times. Many other technical performance is also improved.
