摘　　要：根据工程实践,介绍了常规基带无损伤切换的实现方法并分析了由切换参考标准计算方法不理想带来的问题,提出了一种改进的基于纠错编译码的无损伤切换设计。该方法利用RS译码器给出的错误码字个数作为切换参考信号,实现了快速准确的切换。通过工程实践,验证了方法的可行性。According to engineering application, general methods of based-band lossless handover are introduced and existent problems caused by imperfect method of switch standard are analyzed. An advanced method oflossless handover based on Reed-Solomon error correction codec is raised, which takes error number presented by RS decoder as switch reference signal to perform quick and precise switch. The technical feasibility is proved by engineenng test.
